FIRST ALERT WEATHER: Storm system better organized, rip currents risk increasing

VIDEO: Tropical development likely for storm off coast

A storm system moving towards the Lowcountry coast is better organized and will increase the danger of rip currents, forecasters say.

The National Hurricane Center is tracking the system as Tropical Wave Invest 90-L as it moves north at approximately six miles per hour with maximum winds of 30 mph.

Forecasters expect the system to make a northeasterly turn as it moves along the Atlantic coast, which would take it further away from the Carolina coast.

However, forecast models do not agree on the system's projected path. Some place it close enough to the Lowcountry coast to dump up to two inches of rain, including periods of tropical-style downpours, from Charleston to Myrtle Beach.

Live cameras show an increasingly rougher Atlantic Ocean at Folly Beach, creating bigger waves for surfers but increased dangers for swimmers.

"The risk for rip currents is pretty high and that will continue right on into the upcoming weekend," Live 5 Meteorologist Justin Lock says. Lock says the rip current risk will likely be elevated from moderate to high by Thursday and remain at that level through Sunday.

The hurricane center has increased the chances of the storm forming into a tropical system to 60 percent, up from 40 percent on Tuesday.
