MARYLAND — Bundle up when you head outside Sunday afternoon through Monday morning. The National Weather Service has issued two advisories involving wind meaning it will feel frigid — much chillier than the thermometer may indicate outside.

First, a wind advisory is in effect Sunday afternoon from western Maryland to the Eastern Shore. Later, a wind chill advisory kicks in, from Sunday night through Monday morning, that calls for dangerous cold that will require layers of clothing.

A chill will arrive as winds pick up Sunday afternoon, according to the National Weather Service, which issued a wind advisory that is in effect from 11 a.m. to 7 p.m. on Sunday, Jan. 20.

Gusts may reach up to 50 mph and temperatures will drop below freezing. Secure lightweight and loose objects outside or bring them inside and be aware that wet surfaces may become icy. High-profile vehicles will be difficult to control in strong gusty winds.

The Maryland Transportation Authority issued restrictions and warnings on several bridges due to the wind on Sunday, Jan. 20:

Limited wind restrictions are in effect at the Bay Bridge, Hatem Bridge and Nice/Middleton Bridge. During limited wind restrictions, winds are greater than 40 mph and house trailers, empty box trailers or any vehicle law enforcement officers think may not safely cross are prohibited from traveling on the bridge. Drivers denied passage will be assisted with turning around.

Wind warnings are in effect at the Tydings Bridge and Key Bridge. Wind warnings are issued when winds are 30 to 39 mph. Drivers of the following should use extra caution crossing bridges during wind warnings: house trailers, box trailers, motorcycles, vehicles with cargo on roof racks and any other vehicles subject to high winds.

Dangerous Wind Chills Expected

wind chill advisory has been issued from 10 p.m. Sunday to 11 a.m. Monday.

During that time, wind chills from -5 to -15 degrees are expected. The lowest wind chills are expected early Monday morning. The advisory applies to Baltimore-Washington metropolitan region, central and northern Virginia and southern Maryland.

The Eastern Shore — including Caroline, Cecil, Kent, Queen Anne's and Talbot counties — are under a wind chill advisory from 11 p.m. Sunday to 1 p.m. Sunday calling for wind chills up to -20.

The National Weather Service issues a wind chill advisory when cold air and wind will combine to create low wind chills. People should wear both a hat and gloves if going outside, since frostbite and hypothermia are possible if precautions are not taken.

Frostbite and hypothermia can occur in as little as 30 minutes. Both require medical attention.

Frostbite causes skin damage. It happens when the body is exposed to cold, freezing the skin and tissues underneath it. Symptoms of frostbite include gradual numbness, pale or purple skin, hard or wooden-like skin, or tingling or burning in the affected area.

Hypothermia occurs when the body temperature falls more quickly than it can rise and dips below 95 degrees, according to the Mayo Clinic. Stiffness, confusion, slurred speech, numbness, weak pulse, shivering and changes in motor coordination and levels of consciousness are symptoms.
