Watch for a few showers drifting east-northeast on an otherwise mild and muggy early October evening.

Charleston Weather @chswx.com · 29/09/2026

While it shouldn’t be nearly as significant as yesterday’s flooding was, we should still see some road closures around downtown Charleston as water levels peak between 7.3-7.5’ MLLW around the 10am high tide. Be ready to reroute if you encounter a flooded road!

030

Charleston Weather @chswx.com · 27/09/2026

Another round of minor coastal flooding will be possible with the 9:06 PM high tide. Watch for possible road closures.

030

Charleston Weather @chswx.com · 25/09/2026

Feels like…well, fall! Try to get outside today if you can!

042

Charleston Weather @chswx.com · 24/09/2026

We’ve seen some periods of drizzle from time to time, but more substantial rain with even some thunder is moving across the area from northwest to southeast this afternoon. Be ready for slowdowns as you commute this evening.

031

Charleston Weather @chswx.com · 24/09/2026

Be alert to possible road closures due to tidal flooding if your evening plans take you into downtown Charleston. Water levels should peak around 7.5’, which is moderate flood stage, around the 7:15 PM high tide. Coastal Flood Advisory from 5-10 PM.

061

Charleston Weather @chswx.com · 19/09/2026

Showers and thunderstorms are developing across inland areas of the Tri-County and moving slowly southwestward. Be ready for heavy rain and lightning. When thunder roars, go indoors!

041

Charleston Weather @chswx.com · 19/09/2026

Watching showers and thunderstorms to the north as they sink southward. There’s an outside shot that these could survive into the Tri-County overnight, albeit in a weakening state.

030

Charleston Weather @chswx.com · 16/09/2026

Some refreshing-looking dewpoints in store tomorrow morning as drier air pushes in from the northeast. Dewpoints in the 60s will be a nice change from the summer mugginess, that’s for sure.

050

Charleston Weather @chswx.com · 14/09/2026

Temperatures in the mid-to-upper 80s are common as we head toward lunchtime. The record high of 94° is very much in jeopardy today, and we’re not talking Trebek.

030

Charleston Weather @chswx.com · 11/09/2026

The heavier thunderstorms across the Charleston metro have weakened considerably after moving into sinking air in the wake of the seabreeze. However, if you’re headed west out of Charleston toward Jacksonboro, there’s a flash flood warning there. Be ready for slowdowns heading west on 17.

020

Charleston Weather @chswx.com · 11/09/2026

A new flood advisory stretches from the Charleston/Colleton line through North Charleston and parts of West Ashley up toward Daniel Island and Cainhoy until 6:15 PM. Be cautious as you commute!

020

Charleston Weather @chswx.com · 11/09/2026

Showers and thunderstorms are propagating east and southward as outflow boundaries push toward the coast and into GA. Be ready for rapidly changing conditions along and east of 17!

230

Charleston Weather @chswx.com · 11/09/2026

Another flood advisory in Berkeley County, this one taking in Jamestown, Macedonia, and Alvin until 5PM. Radar estimating 2-3” of rain has fallen along 17-A in Macedonia in the past hour or so with more coming down (though, thankfully, trending lighter).

020

Charleston Weather @chswx.com · 11/09/2026

New Flood Advisory is out for central Berkeley and Dorchester, including Summerville and Moncks Corner, until 5PM. Very heavy, repeating rain falling here, with the potential for flooded roads developing quickly.

050

Charleston Weather @chswx.com · 11/09/2026

Showers and thunderstorms are really starting to congeal in the 17-A corridor with heavy rain and frequent cloud-to-ground lightning. Watch out from Jacksonboro to Summerville to Moncks Corner in particular, with more isolated downpours around Hanahan and Awendaw.

030

Charleston Weather @chswx.com · 11/09/2026

Flood advisory out for Cross and points southwest in Berkeley County. 2”+ of rain has fallen here in the last hour or so, and more continues to fall. Be alert if you travel on Hwy 6 between 176 and the lake.

010

Charleston Weather @chswx.com · 10/09/2026

Showers and thunderstorms moving northeastward through the metro around 10 MPH with brief heavy downpours and a little lightning. Nothing severe but you’ll want to take it easy as visibility may be diminished in heavy rain.

020

Charleston Weather @chswx.com · 10/09/2026

Some minor tidal flooding is expected between 7-10 PM as water levels around the 8:18 PM high tide peak around 7-7.2’. A few closures are possible. Be ready to reroute!

020

Charleston Weather @chswx.com · 10/09/2026

Showers haven’t wasted much time getting going this morning, with the heaviest downpours along the coast east of the Cooper. These will propagate inland as the morning presses on. Be ready for a brief downpour!

030

Charleston Weather @chswx.com · 09/09/2026

Another round of minor coastal flooding is expected between 6-10 PM as water levels peak around 7.2-7.4’ in the harbor with the ~7:30 PM high tide. Once again, be ready to reroute around closed roads.

030

Charleston Weather @chswx.com · 08/09/2026

Heads up, commuters: Moderate salt water flooding is expected in Charleston Harbor with this evening’s high tide around 6:40 PM. Water levels could get high enough to cut off the 61 off-ramp from downtown toward West Ashley. Be ready to use alternate routes!

040

Charleston Weather @chswx.com · 08/09/2026

On & off showers near the coast will continue through midday before the focus for any isolated to scattered activity starts to propagate inland on the seabreeze. Most should stay rain-free today, though.

030

Charleston Weather @chswx.com · 07/09/2026

Coastal Flood Advisory until 8PM. Already seeing water levels well into minor flood stage in Charleston Harbor ahead of the predicted time of high tide around 5:43 PM. Road closures downtown will be quite possible. Be ready to reroute, and never go around barricades!

110

Charleston Weather @chswx.com · 06/09/2026

New warning up that includes Summerville, Ladson, Ridgeville, and St. George until 7PM as strong storms move in from the north and east. 60 MPH winds and quarter-size hail possible.

020

Charleston Weather @chswx.com · 06/09/2026

Storms will continue to slowly move southwest across the area, arriving over Summerville and Goose Creek within the next half hour (provided this one holds up).

020

Charleston Weather @chswx.com · 06/09/2026

Storms continuing to blossom quickly in Berkeley County, with a particularly intense storm still developing over Moncks Corner and propagating westward toward Carnes and Sangaree. Severe Thunderstorm Warning continues until 6:15.

031

Charleston Weather @chswx.com · 06/09/2026

Now a Severe Thunderstorm Warning including Moncks Corner, Goose Creek, Cross, and Bonneau until 6:15 PM. This storm is capable of 60 MPH winds as well as penny-to-nickel-size hail.

031

Charleston Weather @chswx.com · 06/09/2026

Couple storms going up quickly on the north and south sides of Lake Moultrie. The strongest storm is sitting over Moncks Corner, hung up by the inland-moving seabreeze, and should drop a good bit of rain in a short time. Radar already estimating over an inch around Stony Landing.

030

Charleston Weather @chswx.com · 06/09/2026

Watching showers and thunderstorms in the Pee Dee and Midlands as these will head southward, perhaps moving in or igniting additional storms later this evening into tonight across the Tri-County.

030

Charleston Weather @chswx.com · 06/09/2026

It’s been hot and sunny thus far, but we are watching storms to the north and west once again today. A Severe Thunderstorm Watch borders the Tri-County to the northwest; a few strong storms with heavy rain will be possible later today into tonight.

041

Charleston Weather @chswx.com · 06/09/2026

Showers and thunderstorms continue to move southward across the Tri-County, but the window for severe weather has closed. Thus, the Severe Thunderstorm Watch has been canceled early.

030

Charleston Weather @chswx.com · 06/09/2026

Pretty much a continuous light show from this thunderstorm propagating southward through Dorchester and Colleton counties. Satellite-based lightning detection indicating over 200 flashes in the last 15 minutes.

010

Charleston Weather @chswx.com · 06/09/2026

Showers and thunderstorms continue to push southward, generally from Dorchester County and points west as an outflow boundary continues to push southward. A lot of lightning with the storm near Summerville, but nothing reaching severe criteria.

010

Charleston Weather @chswx.com · 02/09/2026

The only notable item on radar is a stray shower in Moncks Corner moving down 17-A toward Cane Bay and Sangaree. A brief downpour is possible but lightning appears unlikely.

030

Charleston Weather @chswx.com · 30/08/2026

Showers and thunderstorms are firing along the seabreeze this afternoon, stretching from Edisto through Cainhoy into far NE Berkeley. These are slow-movers and may dump a quick half-inch of rain

030

Charleston Weather @chswx.com · 30/08/2026

So far it’s generally been quiet this morning, but storms in the Atlantic may make a run to the coast later today along with other popup storms. Heavy rain is the main concern.

052

Charleston Weather @chswx.com · 29/08/2026

We’re largely getting a break from a very soggy start for some, but more rain should develop and move northeast across the area later today. Keep rain gear close and stay alert for possible pockets of flooding this afternoon.

062

Charleston Weather @chswx.com · 28/08/2026

Level 2 out of 4 risk for flash flooding today with storms that should get going by this afternoon. Slow-moving, training storms are the main concern today, with 1-3” of rain a decent bet in some spots. Stay alert for possible Flood Advisories or Flash Flood Warnings.

030

Charleston Weather @chswx.com · 26/08/2026

Some of us got woken up overnight with some heavy thunderstorms, and it looks like we are starting to see more develop already this morning. Could be a soggy day for some, and we’ll need to monitor for a flooding risk.

000

Charleston Weather @chswx.com · 25/08/2026

The seabreeze is trekking inland across Lake Moultrie, kicking off a storm right over Bonneau with heavy rain and some lightning. Elsewhere, things are mostly quiet as storms near Edisto fizzle.

020

Charleston Weather @chswx.com · 24/08/2026

Showers and thunderstorms are firing along the seabreeze, which right now is near the coast and will come inland with time. Heavy downpours down Maybank Highway as well as over downtown Charleston should be short-lived.

150

Charleston Weather @chswx.com · 23/08/2026

Temperatures are generally running in the upper 80s to low 90s this afternoon. Starting to see the seabreeze take some form near the coast, with a shower having already popped. Isolated to scattered showers and storms are still expected later today.

051

Charleston Weather @chswx.com · 23/08/2026

We’ll have some drier air mixing in today which should tamp down a little on the flooding rain risk, but could increase the risk for damaging wind gusts in any storms that can form later today. Keep an eye out for possible changing conditions especially after 3pm.

040

Charleston Weather @chswx.com · 23/08/2026

The Flash Flood Warning will end soon, but an Areal Flood Warning continues across Hanahan, North Charleston, and southern Goose Creek until 3am as standing water continues to drain. No additional rain is expected overnight.

030

Charleston Weather @chswx.com · 23/08/2026

Flood advisory continues for lower Charleston County until 11:45 PM. Still some heavy rain in the area with perhaps another round to come for the islands.

020

Charleston Weather @chswx.com · 23/08/2026

The Flash Flood Warning for downtown has been allowed to expire; it’s still raining, but the heaviest stuff is over there. Still some downpours pushing offshore at Kiawah with a whole lot of lightning in the process.

020

Charleston Weather @chswx.com · 23/08/2026

Flood advisories now extend to Folly Beach, James Island, Johns Island, Seabrook, and Edisto (among others) as very heavy thunderstorms push into the area. A quick couple inches of rain will be possible here, with minor flooding in some spots a decent bet.

020

Charleston Weather @chswx.com · 23/08/2026

A Severe Thunderstorm Warning is up for Colleton and western Charleston counties until 9PM. Storm’s moving ESE at 25 MPH and could impact Adams Run and Hollywood with gusts to 60 MPH.

021

Charleston Weather @chswx.com · 23/08/2026

Storms are quickly rebuilding to the west as the outflow boundary sinks southward and seems to stall out. Flash flood threat is not over yet as rain may try to work back into the metro here soon. Stay alert for additional road closures.
