Wind chill watch NPW – Extreme wind chills that are capable of causing life-threatening medical conditions associated with accelerated heat loss from exposed skin are possible within the next 12 to 48 hours; the apparent temperature and wind speed criteria vary significantly over different county warning areas. This product and its ...
Intense bow echoes responsible for widespread, extensive wind damage are called derechos, and move quickly over large territories. [31] A wake low or a mesoscale low-pressure area forms behind the rain shield (a high pressure system under the rain canopy) of a mature squall line and is sometimes associated with a heat burst.

A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
The length of water over which a given wind blows. Fetch length and wind speed together determine the size of the waves that form on the surface of a body of water; the longer the fetch and the stronger the wind, the more wind energy is imparted to the water surface and the larger the resulting sea state. field mill
The clogging of a vehicle's tailpipe by snow may lead to carbon monoxide buildup inside the cabin. [10] Wet snow and sleet during a winter storm, on the deck of RFA Tidespring south of Plymouth in the English Channel. Depending on the temperature profile in the atmosphere, snow can be either wet or dry. Dry snow, being lighter, is transported ...
Ice shoves can be caused by temperature fluctuations, wind action, or changing water levels [3] and can cause devastation to coastal Arctic communities. Cyclical climate change will also play a role in the formation and frequency of ice shove events; a rise in global temperatures leads to more open water to facilitate ice movement.

When the temperature is below freezing and the wind is calm, such as under a high atmospheric pressure at night in the fall, a thin layer of ice will form over open water of a lake. If the depth of the body of water is large enough, its color is black and can be seen through the ice, thus the name black ice.
