CHARLESTON, S.C. (WCSC) - Tropical storm warnings have been issued for most of the Lowcountry excluding Inland Colleton County. Tropical storm force winds (39 - 73 mph) are possible within the next 36 hours. Plan and prepare now for widespread power outages and wind damage tomorrow. Models are in better agreement that the center should pass offshore through Monday night. Conditions will begin to deteriorate Monday afternoon as winds become gusty along the coast during the lunchtime hour. The winds could gust up to 70 mph along the coastline though by Monday evening, however any shift in the storms center to the west and these winds could shift inland. The official track from NHC seems to favor a middle ground between models, keeping the center offshore of the Lowcountry and making landfall north of the area early Tuesday.
The main concerns tomorrow are flooding and wind damage. Most areas could pick up 2 - 4″ of rain with some isolated spots that could see 6″+. A Flash Flood Watch is in effect for all areas excluding Colleton County. At the same time strong, onshore winds could drive a storm surge to 2-4′. Therefore, coastal areas could see moderate to major flooding. A storm surge watch is in effect for Charleston, coastal Colleton and Georgetown Counties. The amount of rainfall along with the strength of winds will be highly dependent on the track and intensity of the storm.
