  • Freezing Rain:  Rain that freezes when it hits the ground; creating a coating of ice on roads, walkways, trees and power lines.
  • Sleet:  Rain that turns to ice pellets before reaching the ground. Sleet also causes moisture on roads to freeze and become slippery.
  • Snow Squall: Intense periods of moderate to heavy snowfall, in limited duration, accompanied by gusty winds resulting in reduced visibilities and whiteout conditions.
  • Wind Chill:  A measure of how cold people feel due to the combined effect of wind and cold temperatures.
  • Winter Storm Watch: Be prepared.  Severe winter conditions such as heavy snow, sleet or ice may affect your area, but where, when and how much is still uncertain.
  • Winter Storm Warning: Take Action! Heavy snow, sleet or ice is expected in your area.

Prepare:

  • Make sure you have sufficient fuel for cars and generators.
  • Weather-proof doors and windows to trap heat inside your home.

    • Hypothermia: Signs include uncontrollable shivering, memory loss, drowsiness and exhaustion.
  • If using a heater, make sure the area is well ventilated.

  • Excessive Heat Watch: Be prepared. Extremely hot weather may develop across the region.
  • Excessive Heat Warning:  Take Action. Extremely hot weather will develop across the region and will cause significant stress on people and animals unless precautionary measures are taken.
  • Heat Index: A measure of how hot it really feels when relative humidity is factored in with the actual air temperature.
  • Heat Wave:  Prolonged period of excessive heat, often combined with humidity.

Prepare:

  • Install air conditioning systems or know where the nearest air conditioned public place is located.
  • Check your air conditioning system for proper insulation.

Be Safe:

  • Watch for heat illnesses:
    • Heat Cramps: Muscular pains and spasms due to heavy exertion. The first signal that your body is having trouble with the heat.
    • Heat Exhaustion: Blood flow to the skin increases, which decreases blood flow to vital organs and creates a form of mild shock. The condition will worsen if it is not treated.
    • Heat Stroke: The body's temperature control system stops working and causes brain damage. Death may result in some instances.
  • Stay indoors and limit sun exposure as much as possible.
  • Spend the warmest part of the day in the air conditioning. If you do not have air conditioning, considering going to a public location or cooling center that does.
