Tropical Storm Bertha has formed quickly this morning near the coast of South Carolina and it will track inland through North Carolina and Virginia with potentially flooding rainfall.

Bertha is centered 30 miles east-southeast of Charleston, South Carolina, and is moving northwest at 9 mph. It will make landfall in the next few hours and then quickly weaken to a tropical depression and a remnant low as it moves toward North Carolina and western Virginia through this evening.

A tropical storm warning has been issued along the South Carolina coast from Edisto Beach to South Santee River.

Current Information and Projected Path

Despite that expected weakening, Bertha will bring soaking rainfall and possible flooding into parts of the Carolinas and Virginia through Wednesday night. Gusty winds will also accompany this system as it moves inland.

Rainfall totals of 2 to 4 inches (locally up to 8 inches) are possible from eastern and central South Carolina to southeast and central North Carolina and southwest Virginia.

How Did Bertha Form So Quickly?

Bertha formed from a tropical disturbance we've been tracking since Memorial Day weekend near Florida. That disturbance brought more than a foot of rain in three days to Miami, where it triggered on Tuesday.

Its circulation center became much better defined on Doppler radar as it approached the South Carolina coast on Wednesday morning. Buoy reports also indicated tropical-storm-force winds near that center of low pressure.

It was deemed a tropical storm by the National Hurricane Center since it had all the characteristics of a tropical storm. That includes a well-organized area of low pressure, collocated showers and thunderstorms and tropical-storm-force winds.
