BOSTON (AP) — The National Weather Service has issued a flash flood warning for parts of eastern Massachusetts as heavy rains move through the region.

The latest warning is in effect through 6:45 p.m. for southeastern Middlesex County, Suffolk County, northern Norfolk County and a portion of south-central Essex County.

The heavy rain forced some temporary road closures in the Boston area on Tuesday.

Motorists are being advised to avoid driving into areas where water is covering the roadway because it might be difficult to gauge the depth of the water.

A flash flood watch has also been posted through 8 p.m. for much of southern New England.
