The National Weather Service has issued a flash flood watch for this area from Friday morning through Saturday afternoon.

The remnants of Tropical Storm Andrea, combined with a system moving in from the west will bring widespread rain across the tri-state area beginning late tonight and lasting until Saturday.

Rainfall amounts between two and four inches are forecast with the heaviest rain expected Friday afternoon through early Saturday morning. Maximum hourly rates could reach between one and two inches.

These rainfall amounts could lead to flash flooding or poor drainage areas as well as small stream flash flooding, the weather service said.

Gov. Dannel P. Malloy today cautioned residents about Tropical Storm Andrea, which formed in the Gulf of Mexico last night and is expected to have an impact on Connecticut beginning on Friday.

“Hurricane season is indeed upon us, and our storm luck being what it is, residents should start to make preparations for inclement weather,” Mr. Malloy said.

The weather service indicates Tropical Storm Andrea currently has winds in the 60 mph range, which are expected to diminish as it approaches our area.

For Friday, the high temperature is expected to be around 65 degrees, with a low of 59 degrees Friday night.

Saturday’s forecast is for a high of 76 degrees with a chance of showers and a low of 59 degrees Saturday night.
