 Skywarn Radio Frequencies to Monitor  Safety Rules During Severe Weather
Using the information below as a guide, this is the minimum criteria to send to the NWS during any communications. If you do not know how to call the nearest weather service office, dial 9-1-1 and they will pass the information to the NWS for the affected area. Some areas may not use 9-1-1, so inform yourself where to contact if radio contact is not available. You need to be familiar with the area and know your directions; which direction is North
Special Note:
Keep radio transmissions short, direct and leave any frequencies actively in use for weather as chatter free as possible. Use the frequencies page to contact the Wichita NWS, call their toll-free number or dial 9-1-1.

Tornadoes
A tornado is a violent column of air rotating from the base of the clouds and touching the ground. You should be able to see debris at the ground level. This often is occuring with a lowering of a funnel from a wall cloud. Observe for rotation. Remain a safe distance away. Please give the following in your report immediately - slowly, methodically, and brief as possible:
  • Your location - use cross roads or named roads, approx distance and direction from any town; other identifiers are grain elevators
  • Time of observation
  • Your distance and direction from the observed report
  • Define the tornado - "is it a rope, classic or wedge"
  • Direction the tornado is moving, approximate forward speed
Flooding
Rivers, creeks and streams over their banks, water over roads
Winter Weather Reporting is Critical
Observations are not limited to summer storms only.
The NWS is especially interested in reports when snow is falling and radar echoes are not always able to detect the amount of snowfall and conditions on the ground. Please pass on the following information to your weather service office
Sleet, ice
Snow fall on ground too warm to retain snow will allow accumulation of ice on power lines, trees, cars and elevated roads and bridges.
Snow-packed, slush
Report observations of roads that are snow packed and slushy. These can become dangerous conditions if the temperature falls even a few degrees.
Snow fall
Meausrements in excess of 2". Wind can cause reduced visibility and drifting. Report measurements to nearest 1/10"
