Gusts near 50 mph are being recorded at the National Weather Service office at Charleston International Airport. Sustained winds are also worse than forecast earlier, running 25-30 mph.
Forecasters say this should be the worst of the winds but they will continue through the afternoon.
A high wind procedure for Lowcountry bridges has been issued by Charleston County.
The procedure is:
- 30 mph sustained winds. High profile vehicles (such as box-type trucks) advised not use bridges 65 feet or higher. Other vehicles use extreme caution. That 65-feet span includes most larger bridges in the Charleston area including the Folly River bridge.
Sustained winds of 20-30 mph with gusts to 40 mph are expected as part of a storm front moving through the state this afternoon and this evening. The winds should start picking up after noon and into the evening, said meteorologist Vern Beaver with the weather service.
There’s a slight risk of severe weather including isolated tornados this evening. But the storm is expected to lose intensity as it approaches the coast.
A 20 percent chance of rain this afternoon will increase to 90 percent tonight, according to the Weather Service.
Highs will be in the upper 70s with lows about 50.
Thursday: Sunny with a 20 percent chance of showers in the morning. Highs will be in the upper 50s with lows in the upper 30s. West winds will be from 15 to 20 mph with gusts up to 30 mph.
Friday: Sunny, clear skies with highs in the upper 50s and lows about 30. West winds will be from 15 to 20 mph.
