The combination of an approaching cold front and moisture being pulled into the Lowcountry from Tropical Storm Colin has triggered alerts for heavy rainfall and flooding in Charleston and coastal areas. Colin should pass near the South Carolina coast tonight into Tuesday morning. The National Weather Service has issued a Tropical Storm Warning in effect until June 9 at 11:10 EDT.
Depending on its track and intensity, Colin could produce tropical storm force winds of 25-35 mph with gusts to 55 mph, and rainfall totals of 3 to 6 inches with heavier amounts locally. Flash flooding is possible, especially in low lying areas that typically experience flooding during extreme rain events. The situation is somewhat favorable for isolated tornadoes and dangerous beach conditions, including high surf and rip currents.
Coming on the heels of a period of high tides, there is the potential for flooding on and around the Island depending on local rainfall totals. Readers are advised to monitor official sources for up-to-date information, and are encouraged to report exceptional conditions to Town and POA authorities, and Tidelines as well.
We will post additional information as it becomes available.
