For the second day in a row, more than 3,000 state residents are left without power as storms sweep in from the west.

Towns in Litchfield and New Haven counties have dealt with the worst of the storm, as of 8 p.m. There are nearly 2,000 customers without power between Waterbury, Southington, Cheshire and Farmington alone.

Some Fairfield County towns are dealing with fallout from the storm, too. Darien has more than 150 people without service, while further north, in Newton, just under 100 people are dealing with similar problems.

The National Weather Service issued a severe thunderstorm watch for Fairfield, New Haven, Litchfield, Tolland, Hartford and Middlesex counties on Thursday afternoon. The advisory is in effect from noon until midnight Thursday.

Parts of Fairfield and Litchfield counties have been issued a severe thunderstorm warning until about 7:15 p.m. This includes Redding, New Milford, Danbury, Ridgefield and Brookfield.

The NWS is asking people living in these areas to move to an interior room on the lowest floor of a building “for your protection.”

On Wednesday, nearly 3,000 people across the state lost power due to storms with high winds and heavy rains. In Greenwich, the fire department responded to an incident where lightning destroyed one home’s roof.

In parts of West Hartford and Cheshire, some streets became so flooded that some cars had to be abandoned in the water and police had to issue travel warnings. Further south, a fallen tree led to crushing delays along Metro-North lines.
