A stalled front, tropical moisture from the Gulf of Mexico, Atlantic, and some influence from the outer circulation of Hurricane Joaquin will combine to produce substantial, prolonged rainfall through at least Saturday night. As of Saturday morning, we have already seen 3”-7” of rain. Storm Team 2 with WCBD is forecasting an additional 6-12” of rain, with storm totals of 8-15” in some areas.
In addition to the flooding threat from rain, an unusually high tide due to onshore winds and swell energy from Joaquin will occur Saturday at 1:04pm. Isolated tornadoes are possible as well.
The National Weather Service has issued a Flood Watch for the Lowcountry through the weekend as widespread, potentially extreme, flooding is expected. Flash Flood warnings are in place as well for most areas. A coastal flood warning has been issued due to the predicted high tides in excess of 8.1 MLLW.
