Hello everyone, Jarrett Smith here with your Charleston weather forecast for Sunday, August 27th, 2023, along with an update on newly formed Tropical Depression 10.

Sunday will be another warm and muggy late August day in the Lowcountry.

We’ll start the day in the upper 70s, and highs will warm to the low 90s in the afternoon.

Heat indices will run in the low 100s before the sea breeze starts popping some showers and thunderstorms in the afternoon.

Severe weather is not expected, but lightning makes every thunderstorm dangerous, so be sure to head indoors if a storm approaches.

Additionally, brief periods of heavy rain could cause some ponding of water on the roads as well, and later in the day we may see a few storms try to sneak in from the north as well, where more abundant thunderstorms are expected near a stalling cold front.

The main weather story, though, seems to be Tropical Depression 10, which the National Hurricane Center began issuing advisories for at 5pm on Saturday.

As of this recording Saturday evening, 10 was stationary near the Yucatan Peninsula with 30 mph maximum sustained winds.

10 is expected to stay stationary for a fair bit of the weekend, strengthening into a tropical storm and likely taking the name Edalia, before starting to make a move towards Florida, perhaps as a hurricane, as we head into Tuesday.

As usual in the early stages of a tropical cyclone’s life cycle, track guidance has quite spread beyond day 3, making things fairly uncertain in the medium range.

The intensity forecast also could be quite conservative, given the very warm water that Edalia will be traversing as it heads north through the Gulf of Mexico.

The Hurricane Center forecast brings future Edalia across Georgia and into the Midlands during the middle of next week, keeping us on the right side of the system.

And typically, this would increase the risk for coastal flooding and beach erosion, especially with onshore winds ahead of the circulation.

It’s worth reiterating, though, that track guidance ranges from an even further west track to one that has it straddling the coast, and really everything in between.

With that in mind, we’re going to need to see more data before we can start making concrete calls on just how much 10, or future Edalia, will impact us in the Low Country.

Regardless, we look to have a rather unsettled week for much of next week anyway, Edalia or not, thanks to the stalled front nearby.

Coastal flooding was also going to be an issue regardless, thanks to the full moon at Perigee on Wednesday, though Edalia should enhance that flooding threat.

Bottom line here is just to stay tuned to forecast updates periodically over the next few days.

It’s certainly nothing to freak out over by any stretch, and right now looks like the kind of tropical brush we handle pretty well here.

And that was Charleston Weather Daily for August 27th, 2023.
