Special Weather Statement issued April 11 at 3:02AM EDT by NWS Boston/Norton MA

Expires: Sat April 11, 2026, 5:30 PM

Special Weather Statement issued April 11 at 4:31AM EDT by NWS Upton NY

Effective: Sat April 11, 2026, 4:31 AM
Expires: Sat April 11, 2026, 9:00 PM

There is an elevated risk for fire spread today across southern Connecticut. Northwest winds will gust to 25 to 30 mph while relative humidity falls to 25 to 30 percent. These conditions, along with continued drying of fine fuels, could support the rapid spread of any fires that ignite, which could quickly become difficult to control. Conditions should improve this evening as winds diminish and relative humidity increases. Relative humidity on Sunday should fall to 30 to 40 percent. South winds may gust as high as 20 mph in the afternoon. Use caution when handling any potential ignition sources, including machinery, cigarettes and matches. The forecast considers meteorological, fuel, and land conditions, and has been developed in coordination with state fire and land management officials.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
