Special Weather Statement issued January 26 at 7:28PM EST by NWS Upton NY

Effective: Mon January 26, 2026, 7:28 PM
Expires: Mon January 26, 2026, 9:00 PM

Snow showers are moving across portions of Southern Connecticut and Eastern Suffolk County on Long Island this evening. These are expected to continue before 900 PM. In addition, wind gusts up to near 30 mph can be expected at times. This will result in reduced visibilities, down to near 1 to 2 miles at times, as well as a localized quick coating of snow for any relatively heavier snow showers. When encountering these conditions, proceed with extra caution and be prepared for slippery conditions on any untreated surfaces. Motorists should slow down and allow for extra space between vehicles.

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.
