Wednesday’s weather could bring the possibility of extremely high winds rolling through the Lowcountry with gusts up to 45 mph.

Also, weather watchers say there is a chance of conditions that could spark one or two tornadoes in the region as a very strong cold front is moving in Charleston’s direction after already trudging across the South.

The upper Charleston and Berkeley County area is at the highest risk for severe weather this morning, Vern Beaver, meteorologist with the National Weather Service in Charleston, said.

The worst is expected locally between 9 a.m. and noon. But a wind advisory will remain in effect until 5 p.m.

The Weather Service issued a severe thunderstorm warning for souteastern Berkeley County and eastern Charleston County until 12:15 p.m. today.

The morning’s strong winds brought down a tree down on Johns Island near the intersection of River and Fort Trenholm roads, the Weather Service reports.

Weather Service meteorologist Frank Alsheimer said the chance of rain is about 90 percent in the early part of the day.

“It’s going to rain, but it’s not going to last very long,” he said. The worst of it should last about an hour or so and possibly lead to temporary heavy street flooding, he said.

Temperatures will hit into the 60s early on before steadily declining, falling into the 30-degree range by Thursday, Alsheimer said.
