August and September are peak spawning months for red drum in South Carolina!
August and September are peak spawning months for red drum in South Carolina, and successful spawning activity is critical to producing the next generation of red drum, like the fingerling seen below.
If you’d like to help the population rebound, give these adult (or bull) drum a break from fishing pressure during these months. They’ll still be around when temperatures dip and spawning ends in October – after they’ve had a chance to contribute to next year’s crop of young fish.

Weather Alert – TD 2 No Threat to SC, Stormy Late Wednesday, SCDNR
Weather Alert – July 20, 2026
TD 2 No Threat
Over the weekend, the disturbance over the eastern Gulf became Tropical Depression Two. It remains a weak feature south of Panama City, Florida.
It now looks like it will head westward instead of our way. The National Hurricane Center calls for it to move into Louisiana Wednesday afternoon as a weak tropical storm. So, it won’t have any effect on us through the first part of the week. Some computer models show moisture from it being pulled toward us later this week by a cold front moving in. That would be nice; we need the rain.
It’s quiet over the rest of the Atlantic still. The tropical wave near Cabo Verde on Friday is now over the middle of the tropical Atlantic along 40° west, but there is little thunderstorm activity with it. Another wave moving off of Africa today will struggle against dry, stable air and vertical wind shear.
The above loop of visible satellite imagery above shows several features of interest across the North Atlantic and eastern U. S.:
- Tropical Depression Two over the northeastern Gulf.
- A tropical wave near 40° west in the tropical Atlantic
- A band of clouds over North Carolina, Virginia, Tennessee, Kentucky and the Atlantic associated with a stationary front.
- Smoke from Canadian wildfires is spilling southward over the middle of the Atlantic, all the way into the deep tropics.
Stay prepped; hurricane.sc is the place to go for prep advice.
Our Weather This Week:
The front we hoped would bring us active weather early this week has stalled farther north than expected. It’s close enough that the northern half of the state will see substantial coverage of afternoon thunderstorms through Tuesday, and a locally severe storm with damaging wind is possible. A stray storm can’t be ruled out further south, but they will be isolated. Temperatures will remain near to a few degrees above average.
We remain on track to see a more substantial cold front move through on Wednesday afternoon and evening. With that comes more widespread storms and the risk for locally severe storms, especially across the north. Damaging winds will be the primary concern.
It’s looking more likely that the front will stall over us later in the week now rather than push south. There’s a chance that the Upstate sees a nice day with low humidity on Friday, but don’t count on it. Otherwise, we’ll see limited sunshine with widespread showers and thunderstorms, mostly during the afternoon. If tropical moisture from TD Two becomes involved, torrential downpours and a flash-flooding risk would become a concern.

Weather Alert – Watching the Gulf, More Severe Thunderstorms Possible, SCDNR
Watching the Gulf, More Severe Thunderstorms Possible 
Weather Alert – July 17, 2026
Watching the Gulf
Finally, we again have some signs of life in the Atlantic tropics. There are two areas of interest out there today. One is close to home, and the other is way out there over the eastern Atlantic.
Here’s the National Hurricane Center’s (NHC’s) Seven Day Graphical Tropical Weather Outlook from Friday afternoon.
Our primary concern is a blob of thunderstorms that has erupted over the far western Gulf over the last 24 hours, associated with an upper-level low over the area. The area could (NHC gives it a 20 percent chance) evolve into a tropical cyclone as it wanders around the northeastern Gulf. Whether or not it becomes a tropical depression or storm, the most likely track will be over Florida and near the East Coast. The impacts will depend on the track and how strong of a feature it becomes, both of which are very uncertain right now. It could remain too far offshore to affect us, a disorganized plume of moisture that contributes to rain along our Coastal Plain early next week (ideal because we need the rain) or a tropical depression or weak tropical storm that brings our coastal areas heavy rain, gusty winds, a small storm surge along with a risk for isolated tornadoes. Another alternate scenario some of the computer models show is that it drifts westward instead and becomes more of a concern for the central Gulf Coast than for us. This feature will definitely have our attention over the weekend; if it will affect us, that will happen Monday night through Tuesday night.
The loop of visible satellite imagery above shows several features of interest across the North Atlantic and eastern U. S.:
- Thunderstorms are clustering around a developing low-pressure area over the northeastern Gulf.
- Low pressure along a tropical wave is centered near Cabo Verde and moving northeastward.
- A tropical wave is near 45° west, drifting westward slowly.
- Bands of smoke from large wildfires west of Hudson Bay can be seen from Michigan and Ohio through the Mid-Atlantic region and over the Atlantic north and northeast of Bermuda.
The other area of concern is over the eastern Atlantic, where a weak low-pressure area has formed along a tropical wave that recently emerged from Africa. It looks decent on satellite imagery with a swirl of clouds and some associated thunderstorms. However, it’s moving northwestward toward dry and stable air. So, it’s a long shot (10 percent chance, according to NHC) to become a tropical depression or a weak tropical storm while causing squally weather in Cabo Verde this weekend. After that, it likely remains a weak feature as it moves toward the central North Atlantic. It looks, to borrow a phrase from my favorite author, mostly harmless.
There are no other features of interest over the Atlantic today. A tropical wave is near 45° west over the middle of the tropical Atlantic, but it is very weak and unlikely to raise any ruckus in the coming days as it drifts westward.
Since there’s a small chance we’ll have to deal with a tropical storm next week, you’ll want to use the weekend to make sure your hurricane kits are properly stocked. As always, hurricane.sc is the place to go for prep advice.
More Severe Thunderstorms Possible
Another weekend, another cold front: our late week heat will ease through Sunday as another cold front moves in. We’ll see sparse coverage of routine afternoon thunderstorms this afternoon and Saturday afternoon, though keep in mind that sometimes our summertime storms become severe with isolated damaging wind. The Upstate has the best chance to see a severe storm.
By Sunday, the approaching cold front will be over our tomato-and-vinegar-loving northern neighbors, which will increase afternoon thunderstorm coverage over the northern half of our state and increase the severe storm risk in that area. Locally damaging winds will be the primary concern with the storms.
Here’s the Storm Prediction Center’s Day 3 Severe Weather Outlook for South Carolina, covering Sunday and Sunday night.
The front will become stationary and start to decay over us on Monday, so look for widespread showers and thunderstorms that could start to pop up before midday. Once again, a locally severe storm is possible. It will be the least hot day of the next few with highs only in the upper 80s and lower 90s.
Tuesday brings us less widespread thunderstorms and more heat; highs will be 90-95° across the state. However, the feature in the Gulf is the wild card for the day, as we’ll feel its impacts Monday night through Tuesday night if it tracks toward us. Our coastal areas are most likely to see it cooler and wetter; again, low-end wind, surge, rain and tornado risk is the worst-case scenario near our coast if the feature becomes a tropical cyclone.
On Wednesday, we have better-than-usual agreement among the computer models that another cold front will move in. The front is likely to bring showers and thunderstorms, and there is a chance of severe storms again if it moves through during the afternoon and evening.
We have a chance of unusually pleasant weather for at least part of the state later next week, as the weather pattern then will favor the cold front pushing much farther south than we typically see in July. Computer models tell us the front will stall to our south and east Thursday into Friday, allowing a drier air mass to move in with temperatures running near or slightly below average. 90° with low humidity is a pretty good deal for us in late July, so I’ll be rooting for that. However, climatology isn’t on our side, so don’t be surprised if the front stalls farther north and west than the models indicate, resulting in at least part of the state seeing scattered showers and thunderstorms. Of course, with most of the state still in a drought, more rain chances are a good deal, too.
On the satellite loop above, you’ll see areas of smoke from wildfires in Canada streaming by to our north. Some of it is sneaking into the Pee Dee; you may notice some haziness that way this afternoon. The smoke will mostly remain north of us through the weekend but it may shift southward toward us next week, especially later in the week.
Speaking of drought, if you have ever wondered how we define drought and its severity, I can tell you about an opportunity to learn more. The National Drought Mitigation Center (located at the University of Nebraska) will hold an online workshop to explain how the U.S. Drought Monitor works. If you’re interested, you can read more and sign up here: NDMC’s U. S. Drought Monitor 101 signup. The workshop will be held on August 13, from 3-4 p.m. Eastern Time.

Weather Alert – Tropics Quiet, Get Ready To Roast, SCDNR
Weather Alert – June 26, 2026
Tropics Quiet
The Atlantic tropics remain quiet today and are likely to stay that way for a while, at least through Independence Day. A few tropical waves are present: one over the western Caribbean Sea near 80° west, another east of the Lesser Antilles, slanted between 45° and 50° west, and the third over the eastern tropical Atlantic near 28° west.
This loop of visible satellite images shows the weather features of interest
over the Atlantic Basin today.Image Source: University of Wisconsin RealEarth
None of these waves shows any promise for development; strong westerly winds aloft are causing vertical shear over the entire Atlantic Main Development Region (the area between 10° north and 20° north), and sinking air is present over the Atlantic as well, thanks to the Madden-Julian Oscillation.
So, it’s no surprise that no computer models indicate a significant chance for any developments in the deep tropics over the next two weeks. If we were to see a tropical cyclone form, it would come from spins developing along stationary fronts off the East Coast over the Gulf. The odds of this happening are low.
We’re always happy to see tranquility in the Atlantic tropics, and we hope it stays that way. However, it’s a long hurricane season, and we just got started. It’s important to be ready for the risk we face from hurricanes, and if you need readiness advice, SCEMD has you covered at hurricane.sc.
SC Weather Highlights for the next week or so:
The big story for us, as well as our neighbors in this part of the country, will be the intense heat that we’re about to see. A strong upper-level ridge (a northward buckling of the jet stream) will form over this part of the country over the weekend and early next week; it will suppress thunderstorms and promote above-average temperatures until it breaks down about a week later.
Translation: It’s about to turn into Satan’s back porch ’round these here parts.
Today we’re under the influence of an upper-level disturbance that likely brings us widespread afternoon and evening showers and thunderstorms. The severe storm risk is low but not zero.
Temperatures tick upward on Saturday with sparse coverage of afternoon showers and thunderstorms. Highs will mainly be in the lower to middle 90s around the state.
Sunday looks even hotter, with 95-100° highs for most of the state, the Upstate looks slightly less hot; the heat index will peak at 105-110° across most of the state.
A weak cold front moves in Sunday night, becomes stationary, then fizzles out Monday into Monday night. That will generate a scattering of showers and thunderstorms. This results in a less-hot Monday, with highs mainly in the lower to middle 90s. Thunderstorm coverage will be lower on Tuesday; perhaps it’s slightly hotter as a result.
After that, the misery begins in earnest; the upper ridge will suppress thunderstorms and promote intense heat from Wednesday through at least Independence Day. Here’s the forecast highs for Thursday from the National Weather Service, which is as far out as their specific forecasts go:
Friday and Independence Day could be even hotter. The computer models show the hot weather pattern will break down after that, but disagree on when. Some say we’ll cool down starting next Sunday, some keep us searing on the grill through around next Tuesday. Either way, we’re all going to be well done by the time the upcoming heat wave ends.

Equipment Arriving for Georgetown Harbor Dredging, Georgetown, SC
Thanks to Chris Carroll of Harborwalk Marina for this information regarding the dredging of Georgetown Harbor.
Harborwalk Marina, A CRUISERS NET SPONSOR, is only a boardwalk stroll away from Georgetown’s Historic District for history, entertainment, great food, and shopping. Harborwalk Marina is the third marina on your starboard side as you enter the very protected waters of Georgetown.
Equipment Arriving for Georgetown Harbor Dredging
Expect to see dredging equipment start to arrive in the Georgetown Harbor by the end of the week as preparations get underway for the long awaited dredging project to begin.The goal of the project – the first of its kind in nearly two decades – is to restore the harbor to a depth of 12 feet.Sonja Carter, Army Corps of Engineers project manager, addressed Georgetown County Council Tuesday night.
She said the dredging is needed so recreational and commercial vessels can get to the downtown area. She said the areas to be dredged will be along the Harborwalk and the steel mill channel.It is also needed as the redevelopment of the port and the steel mill properties takes place.Carter said a total of 560,000 cubic yards of material is expected to be removed during the project, which is expected to begin in mid-July and end by the end of August or early September.
“We expect it to take 6-8 weeks and then we will be out of your harbor,” she said.
She said the dredging will take place around the clock.
“You will hear noise and see the equipment,” she said, adding the channel is expected to be passable for boats during the entire project.
Carter said a study conducted showed there will be no significant impact to the environment as a result of the project.
“All environmental compliance will be followed,” Carter said.
The Army Corps has not maintained the harbor dredging since 2008. That has resulted in sediment buildup reducing the depth of the channel to around 2 feet in many areas.
Congress appropriated $6.5 million in 2024 for the harbor restoration project.Click Here To View the Cruisers’ Net’s South Carolina Marina Directory Listing For Harborwalk Marina

Weather Alert – Here Comes Arthur, SCDNR
Weather Alert – June 18, 2026
Here Comes Arthur
Key Points:
- Arthur’s remnants will bring a risk for locally damaging wind, isolated tornadoes and flooding rain to South Carolina tonight.
- The damaging wind and tornado risk is greatest over the area between I-20 and I-85, and minor wind damage could be widespread in this area. However, a risk will be present over the entire state.
- The risk of flooding rain is greatest over the northwestern quadrant of the state, but isolated flash flooding is possible elsewhere.
- Behind the storm, the weekend is looking mainly rain-free, except for a chance for a shower and thunderstorm over the southern Lowcountry Saturday and stray afternoon thunderstorms over the Upstate on Sunday.
Arthur’s remnants, at press time centered close to Phil Robertson’s backyard, are heading east-northeastward and will cross South Carolina tonight and early Friday. Flooding rain, strong winds and isolated tornadoes are all threats as it moves through.

Ahead of Arthur, a weak warm front will trigger showers and thunderstorms this afternoon and evening in the soupy air mass present over the Palmetto State. Stronger storms can cause locally damaging winds. Hail and tornado risks will be minimal through early evening with these thunderstorms.

Arthur’s remnants will arrive over the western Upstate this evening and rake across the state through the night and exit offshore by around 10 a.m. Friday. There remains some uncertainty about where the heaviest rain will fall, which areas will be hit by the strongest winds, and which areas will be subject to a tornado threat. The expected storm track has shifted slightly northward today, bringing the zone of greatest concern for damaging wind and tornadoes to areas along and between I-20 and I-85.
The Storm Prediction Center’s Day 1 (through tonight) Severe Weather Outlook graphic for South Carolina has the entire state covered with a band of level 2 of 5 between I-20 and I-85 due to an elevated tornado and wind risk for that area.
The risk of excessive rainfall and resulting flash flooding covers the entire state, but the quadrant roughly between I-20 and I-77 is at greatest risk.
Rainfall over the Upstate and vicinity through early Saturday will generally be 1-3 inches, with local totals of 4-5 inches. The I-20 Corridor is looking at 1-2 inches, locally up to 3 inches. Over the Coastal Plain, the forecast is for generally half an inch to an inch; locally, up to 2 inches is possible. This will put another nice dent in our drought, especially in the Upstate.
The rainfall forecast from the Weather Prediction Center for now through 2 p.m. Saturday shows a major soaking over the Upstate and vicinity.

Behind Arthur, a cold front will move through later Friday into Friday evening. It will trigger scattered showers and thunderstorms; a locally severe storm with damaging wind can’t be ruled out.
Behind all this mess, Saturday looks to be a nice day for most of the state for mid-June with lower humidity. The exception will be the southernmost part of the state; the cold front turns stationary over or just south of the Lowcountry, so that area has a chance of showers or thunderstorms. Sunday looks hotter and more humid with a pop-up thunderstorm possible over the Upstate — more typical summer weather for the start of astronomical summer (summer starts June 1 in every meteorologist’s mind) and Father’s Day.
Get ready for impacts tonight by reviewing severe storm and tornado safety tips and flooding safety tips. A tornado threat coming in the middle of the night is always problematic; be sure you have multiple ways to receive warnings that will wake you up.
Again, think of this as a tropical warning shot; take some time to get your hurricane prep work done. If you need help with that, visit hurricane.sc.
