Reference Material

Tornado / Funnel Clouds

Is there contact with the ground? Or is it a funnel cloud (aloft)? Are there indications of rotation?  Are there signs of debris? Are there reports of damage from that area? What direction was it heading?  Is it still on the ground? Tornado   Funnel Cloud   Wall Cloud

Damaging Wind

Is the report speed MEASURED or ESTIMATED? What is the extent of damage? Are trees damaged or uprooted? "Funnel clouds" are often reported incorrectly by the public from shelf clouds. Shelf Cloud vs. Wall Cloud Peak Wind reference (web page) Shelf Cloud   Shelf Cloud

Hail

What size are the largest hail stones? Avoid "marble" sized hail - were they dime, nickel, quarter, golf ball? Hail size reference (web page) Hail size reference chart Hail Sizes

Flood

What is the depth of water? Is the water stationary or moving? What impact are flood waters having? Roads closed? How much rain has fallen?

Winter

How much snow or ice has accumulated? Are roads snow covered? Drifting snow? Travel conditions? How is snow plowing progress? Measuring Snowfall graphic Snowfall Reports
