Hurricane Idalia, which as of this writing was a strong Category 2 hurricane with 100 MPH maximum winds, will make landfall as a major hurricane in Florida later Tuesday or early Wednesday. From there, Idalia will turn more northeast, bringing heavy rain, gusty winds, coastal and freshwater flooding, and the risk for a tornado or two within rain bands to the area later Wednesday into early Thursday morning. Trends have been for the storm to track a little more inland of the coast than we’ve seen forecasted in the past day or so, and there is pretty good agreement that this will be the case, expanding the heavy rain threat further inland along with the tornado threat in the evening. Here’s a full rundown of what to expect.
Tuesday will be another warm and muggy day as we prepare for Idalia’s arrival in the Lowcountry. We start the day in the mid-70s and warm to around 90° with heat indices approaching 100° within the increasingly tropical airmass. Showers and thunderstorms should begin to fire along the seabreeze in the afternoon and become somewhat numerous at times. Heavy rain capable of minor flooding will be possible. We’ll also need to watch the risk for coastal flooding in the evening, with minor to moderate flooding possible as water levels approaching 7.5′ with the 7:31 PM high tide. Due to the Storm Surge Watch in effect, there will be no Coastal Flood Advisory, so keep that in mind.
