According to the National Weather Service Tropical Storm, Isaias has progressed from a 'Watch' into a 'Warning' which means the storm is a bit stronger than originally forecasted.

The storm has picked up speed in the Carolinas and has become a hurricane again, but as it heads to Connecticut it should be downgraded back to a tropical storm but now, Garry Lessor, chief meteorologist for Western CT University tells us a Tropical Storm Warning is more serious than a 'Watch.'

The storm has picked up speed in the Carolinas and has become a hurricane again but as it heads to Connecticut will be downgraded back to a tropical storm. Not only will rainfall be an issue but Lessor tells us that we could see sustained winds up to 65 mph most of the day on Tuesday.

According to weather.com, potential impacts for Connecticut during the Monday night to Wednesday time period include heavy downpours and gusty winds. Weather.gov is predicting possible heavy rainfall during the day on Tuesday with possible tropical storm conditions on Tuesday night.

The Coast Guard has urged commercial and recreational boaters on Connecticut's southern coast to prepare for the possibilities of high surf, heavy wind, and heavy rainfall along with possible coastal flooding.
