Wind chill advisory

The Riverhead Senior Center will be open as a warming center today until 4 p.m. and tomorrow from 8 a.m. to 4 p.m., Riverhead Town Police said in a weather advisory. 

A blast of arctic weather is headed this way Friday night into Saturday morning as a “ dangerously cold air mass” settles over the region, bringing with it wind chill values that may fall to as low as 15 below zero.

Wind chill values of 15 to 24 below zero will prevail this morning, as 15 to 25 mph winds, gusting to 35 mph, combine with an arctic cold air mass, according to the National Weather Service.

“The frigid conditions will be dangerous to those venturing outside,” the National Weather Service said. Prolonged exposure may cause frostbite and hypothermia, the weather service said.

A wind chill advisory is in effect from midnight until 10 a.m. on Feb. 20, 2015 for wind chill values as low as 17 below zero.

The blizzard warning was canceled overnight but a high wind warning, wind chill advisory and winter weather advisory remain in effect for eastern Long Island this morning.

A wind chill advisory remains in effect until 9 o’clock this morning, as “dangerously cold air” — with wind chill readings as low as 15-below — envelops the region, according to the National Weather Service.
