With sunshine and mild summer temperatures forecast, a handful of state parks were closed temporarily Sunday as their parking lots swelled to capacity.

The closures of three state parks before 11 a.m. came as thousands of state residents entered their sixth day without power in the wake of Tropical Storm Isaias.

The closed parks were Rocky Neck State Park in East Lyme, Millers Pond State Park in Haddam and Mount Tom State Park in Litchfield.

Two dozen parks and campgrounds remained closed entirely after the Aug. 4 storm, which which at its peak left around 700,000 without electricity. Several other parks were partly closed or opened without electricity.

Those closures included Lake Waramaug State Park and Campground in Washington and Kettletown State Park and Campground— both popular destinations.

The forecast for Sunday called for mostly sunny skies with highs in the mid 80’s and a light breeze. Temperatures are expected to fall to the low 70’s overnight, with sun and temperatures rising back up to the low 90’s in the rest of the week.

Friday and saturday could bring showers, with mostly cloudy conditions and highs in the mid-80’s.
