Hillsborough, Pasco, Pinellas and Sarasota counties are opening their cold weather shelters on Monday and Tuesday.

Manatee County’s Emergency Management Division said it coordinated with the Salvation Army to open cold weather shelter space at their 1204 14th St. West location in Bradenton this week. Doors open at 6 p.m. each night through Thursday. County officials said this space is in addition to the daily sheltering program.

With Tuesday's First Alert Weather Day​, and temperatures expected to drop into the single digits Tuesday night into Wednesday morning, the City and County of Denver activated its Cold Weather Shelter plan.

Several cold weather shelters are opening their doors this week in Escambia County as a cold weather advisory is in effect. The National Weather Service of Mobile issued a cold weather advisory to begin Monday night through mid-morning on Tuesday.

Volusia will open a shelter Monday through Wednesday, too. Temperatures are expected to dive into the mid-30s.

For many in Denver and eastern Colorado, the coldest low temperatures in nearly a year are on the way. The forecasted low for Denver should drop close to 7 degrees.

Clouds will continue to clear out Tuesday night. This will aid in a rapid drop in temperatures down to the single digits, according to FOX31 Pinpoint Weather Chief Meteorologist Dave Fraser.
