Ready for another drenching?

Long Island can expect an average of 2 to 3 1/2 inches of rainfall starting early Thursday morning and lasting into the evening, the National Weather Service said.

We can expect thunder and wind gusts of up to 35 mph, said Peter Wichrowski, a weather service meteorologist based in Upton. A flood watch for the area is in effect through Friday night.

Thursday's storm is related to the massive line of fierce weather walloping the Midwest and mid-Atlantic, but Long Island is expected to avoid the most severe impacts.

The remnants of Tropical Storm Andrea drenched Long Island on June 7, dumping about 3 inches in most places.
