Winnebago County SKYWARN is held on 147.195   when severe weather is in our area.
Note: You can listen to the SKYWARN on your scanners and radios. But to participate you need your ham radio license.  More info at  http://rockfordscanner.com/rockford-area-ham-radio-page/


Here’s how to properly report the various severe weather hazards.

• Funnel clouds and tornadoes:
Funnel clouds are not in contact with the ground. Tornadoes are in contact with the ground, but note that tornadoes are the wind, not the cloud! Even if the tell-tale condensation funnel is not extending all the way to the ground, swirling dirt or debris being kicked up at ground level means that a tornado is in progress.

Damaging wind gusts:
Unless you have a home or portable anemometer to directly measure the wind speed, whenever possible report the damage that occurred to correlate with the wind speed instead of estimating wind gust speed.

• Hail size:
Either measure or estimate to the size of a coin or ball, NOT MARBLE size.

Flooding:
Know the difference between flash flooding (>= 6″ depth of moving water, >= 3 ft depth of standing/ponded water) and flooding (< 6″ depth moving water, < 3 ft depth of standing/ponded water) when reporting.

REMEMBER: Safety First!
Include your location (to the nearest intersection if possible) and the time the event occurred when sharing reports.


Thunderstorm Criteria:

    • Tornadoes or funnel clouds (be very wary of look-alikes; watch for rotation)
      • Rotating appendage from a cumulonimbus cloud not touching the ground
    • Wall clouds, especially if they are rotating
  • Hail (Be specific with regard to size)
    • Report any size and specify diameter.
    • Quarter (1″) and larger is severe!
    • Hail Sizes Chart
  • Wind Gusts
    • 40 mph or greater; specify whether estimated or recorded
    • large branches downed (specify diameter of branch)
    • Trees/power lines downed
    • Structural damage to buildings (roof, windows, etc.)
  • Rainfall
    • 1 inch or greater in an hour and every inch thereafter
    • 2 inches or greater storm total
  • Flooding
    • Report any flooding
    • Basement, road
    • Streams/Rivers — also, when nearing bankfull
    • Street (depth of water)

Tornado: A violently rotating column of air extending from a thunderstorm cloud to the ground. The Enhanced Fujita Tornado Intensity Scale is used to categorize tornadoes

Funnel Cloud: A condensation funnel extending from the base of a towering cumulus or cumulonimbus, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.


Wind Damage

What kind of damage did the wind cause?

  • Small limbs down (less than 2″ in diameter)
  • Large limbs/branches down (more than 2″ in diameter)
  • Trees snapped or uprooted
  • Power lines down
  • Structural damage and/or Roof damage

Hail

What size hail did you see?

  • Pea Size: 0.25 inches
  • Small Marble: 0.50 inches
  • Penny: 0.75 inches
  • Nickel: 0.88 inches
    Any hail size at or above a Quarter (1.00 inches) is severe thunderstorm criteria:
  • Quarter: 1.00 inches
  • Half Dollar: 1.25 inches
  • Ping Pong Ball: 1.50
  • Golf Ball: 1.75 inches
  • Hen Egg: 2.00 inches
  • Tennis Ball: 2.50 inches
  • Baseball: 2.75 inches
  • Grapefruit: 4.00 inches
  • Softball: 4.50 inches

Flooding:

What kind of flooding was observed?

  • Minor street flooding
  • Low water crossings flooded
  • Widespread flooding
  • Home/Business flooded
  • Creek/Stream out of banks
  • River out of banks
