Isaias Brings Flash Flood Potential and Gusty Wind

An isolated tornado cannot be ruled out...
Posted at 7:30 PM, Aug 03, 2020

Isaias continues to hug the South Carolina coast this evening, moving to the north-northeast at 16mph. Maximum sustained winds have increased to 75mph-- which means the storm has re-intensified to a category 1 hurricane. There is still a lot of dry air intrusion on the southwestern side of the storm...which is why the storm isn't symmetrical. There are signs in the latest radar scans that the storm is trying to tighten it's core. A tropical storm warning is already in effect for most of the state through tomorrow.


Showers will continue off and on tonight with rain on tap for the morning drive. The most unstable part of the day will occur between mid morning and mid afternoon as the center will move though the area. The center (and to the right of the center) is where the heaviest rain, strongest winds, and greatest potential for an isolated tornado lies.


A Flash Flood Warning in effect for the area through midnight Wednesday morning. We are expecting widespread areas receiving 3-5". In isolated locations 7+" will be possible.
