Freeze Watch issued January 26 at 12:36PM EST until January 28 at 9:00AM EST by NWS Jacksonville FL

Effective: Mon January 26, 2026, 12:36 PM
Expires: Tue January 27, 2026, 10:00 AM

* WHAT...For the Cold Weather Advisory, very cold wind chills as low as 16 expected. For the Freeze Warning, a hard freeze with temperatures as low as 24 expected. For the Freeze Watch, sub-freezing temperatures as low as 27 possible. * WHERE...Portions of northeast and northern Florida. * WHEN...For the Cold Weather Advisory, from 10 PM this evening to 10 AM EST Tuesday. For the Freeze Warning, from 1 AM to 10 AM EST Tuesday. For the Freeze Watch, from Tuesday evening through Wednesday morning. * IMPACTS...The cold wind chills as low as 16 degrees could result in hypothermia or frostbite if precautions are not taken. Wind chill values can lead to hypothermia with prolonged exposure. Appropriate action should be taken to ensure tender vegetation and outdoor pets have adequate protection from the cold temperatures. Young children, the elderly and the homeless are especially vulnerable to the cold. Take measures to protect them.

Use caution while traveling outside. Wear appropriate clothing, a hat, and gloves. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing. Take steps now to protect tender plants from the cold.

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.
