There are no active Watches, Warnings or Advisories



Your severe weather report should be detailed but concise, and should address the following questions:
  1. WHAT did you see?
    • Report the location/approximate location of the event. Be sure to distinguish clearly between where you are and where the event is thought to be happening ("I am across the street west of the Bruceton water tower. The tornado looks to be about 5 miles to my northwest").
  2. WHERE did you see it?
    • Be sure that reports that are relayed through multiple sources carry the time of the event, NOT the report time.
  3. WHEN did you see it?
    • Any other details that are important - How long did it last? Direction of travel? Was there damage? etc.
NEVER report a Funnel Cloud as a TORNADO if you cannot observe the bottom part of the funnel cloud. If you cannot determine that the funnel cloud is touching the ground or visually see evidence that a debris cloud is present then it should be reported as a Funnel Cloud NOT a Tornado.

Tornado Hail ¾-inch diameter or larger Hail ½-inch diameter or larger
Funnel Cloud Wind Speed ≥ 58 mph Wind speed ≥ 40 mph
Rotating Wall Cloud Persistent non-rotating wall cloud Cloud features suggesting storm organization
Flash Flooding Rainfall ≥ 1 inch/hour and each hour after that Total Rainfall ≥ 2"
Flooding of any type Ice accumulation of ⅛" or more Snowfall at or exceeding 2"


The size of hailstones is best determined by measuring their diameter with a ruler. In the absence of a ruler, hailstone size is often visually estimated by comparing its size to that of known objects, such as coins. Please Note: Using objects such as hen's eggs and marbles for comparing hailstone size is imprecise, due to their varied dimensions. Please use the chart below to define the hailstone size when reporting.

When calling in hail reports please notate if the size is an actual measurement or an estimated size. This is very important.
Pea Size≤ ¼-inch
SMALL Marble Size½-inch
Penny Size¾-inch
Nickel Size⅞-inch
Quarter Size1-inch
Half Dollar Size1¼-inch
Ping-Pong Size1½-inch
Golf Ball Size1¾-inch
Lime Sized2-inch
Tennis Ball Size2½-inch
Baseball Size2¾-inch
Large Apple Size3-inch
Softball Size4-inch
Grapefruit Size4½-inch
CD/DVD Size≥4¾-5 inch
*** Please DO NOT use the phrase "marble size" when describing hail because marbles come in different sizes. Note SMALL marble where the hail is smaller than a dime. ***
