Tropical Storm Isaias: Delaware forecasts call for heavy rain starting Monday night

The National Weather Service has issued a tropical storm watch for Delaware and much of the I-95 corridor for the next 48 hours, with the heaviest winds and rain expected Tuesday.

Tropical Storm Isaias presented less of a threat than initially anticipated when it reached southeast Florida Sunday, but still produced wind gusts of up to 70 mph and heavy rain.

As it crawls north, potentially making landfall in the Carolinas Monday night, Isaias is no longer forecast to reach hurricane strength. Flash flooding is one of the primary concerns — a flash flood watch is also in effect for Delaware.

In Delaware, rain is expected beginning Monday night and throughout the day Tuesday.

The National Weather Service said on Sunday the most likely time of arrival for tropical storm winds in Delaware is mid-day Tuesday, but strong winds could come sooner in the morning.

The weather service is predicting Delaware to receive between two and six inches of rain and experience winds of up to 60 mph. Increased swells and rip currents are expected on the coasts until at least Wednesday.

As part of its tropical storm watch, the National Weather Service warned of potential damage to porches, awnings, carports, sheds, unanchored mobile homes and other unsecured lightweight objects. Tree damage and power outages are also possible.

Forecasters are also watching another system far out on the Atlantic. Showers and thunderstorms associated with a tropical system a few hundred miles east of the Leeward Islands are organizing and have a 60% chance of becoming a tropical cyclone over the next five days.
