Hello everyone, Jared Smith here with your Charleston weather forecast for Tuesday, September 26, 2023.

We have one more unseasonably warm day ahead on Tuesday before changes arrive later in the day and for the rest of the week.

We start Tuesday rather warm, with upper 60s to low 70s temperatures across much of the metro, and even warmer lows are possible at the beaches.

Highs will then head into the upper 80s despite increasing cloud cover, and as we get further into the afternoon we should start to see some showers break out, though they won’t be terribly widespread, nor will they be terribly heavy.

The main weather concern for Tuesday will be the potential for moderate flooding around the 6-17pm high tide.

This may be impactful for folks traveling out of downtown towards West Ashley during the evening hours, as moderate flood stage is generally when we start to see the off ramp from 17 to 61 get covered by water.

So bottom line here is to be ready for delays as you commute home Tuesday evening.

And the risk for coastal flooding will continue with each high tide through at least Thursday, and probably beyond, as we get closer to the full moon and northeasterly winds persist.

Major coastal flooding will be possible Wednesday and Thursday evenings, with minor to moderate flooding possible in the mornings, so be alert to the possibility of travel troubles especially if downtown is in your plans.

The upside of the northeasterly winds is that we get more seasonable temperatures starting Wednesday.

Expect highs to range from the upper 70s to low 80s each day into the weekend.

Shower chances peak Wednesday and Thursday before gradually starting to taper off Friday as the coastal trough begins to move away.

In the tropics, Tropical Storm Philippe continues to struggle against wind shear as it moves west northwest across the central Atlantic.

Shear should continue to keep working on Philippe, and despite warm waters, it should stay generally as a weak tropical storm as a result.

Philippe poses no imminent threat to land, much less the low country.

The other area of interest in the Atlantic is Invest 91L, situated southwest of the Cabo Verde Islands.

It should become our next depression over the next few days, and appears likely to be our next name storm as well.

If that happens, the next name on the list is Rina.

It too does not appear to pose any imminent risks to land.

I’ll tell you, after Rina, the name list starts to get really thin.

We only have Sean, Tammy, Vince, and Whitney left, and then we get into the supplemental names.

Remember, after 2020, we stopped using the Greek alphabet for the extended list of hurricane names.

Hopefully, we don’t get that far in.

And that was Charleston Weather Daily for September 25th, 2023.

I’m Jared Smith.
