PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, dont drown when encountering flooded roads. Most flood 
deaths occur in vehicles. Do not drive on or attempt to cross 
flooded roads, find an alternate route. Roads and driveways may be 
damaged or washed out in places.

Remain alert for flooding of creeks, streams, and normally dry 
coulees even in areas not receiving rainfall downstream of the burn 
area. These can become raging killer currents in a matter of minutes 
even from distant rainfall upstream.

Please report observed flooding to local emergency officials and 
request they pass the information to the National Weather Service in 
Billings.
