Shelby County Emergency Management Coordinator Bob Seivert says the extremely dry and windy conditions forecast this week have prompted his department to issue a “High Fire Danger” warning in Shelby County. Seivert says outdoor burning should be avoided, but if you must conduct a controlled burn, call 712-755-2124 prior to igniting of the burn.
THE NATIONAL WEATHER SERVICE IN DES MOINES HAS CANCELLED THE FIRE
WEATHER WATCH ISSUED FOR PARTS OF WESTERN IOWA. WINDS SPEEDS ARE STILL EXPECTED TO INCREASE TO 25 TO 35 MPH BY EARLY AFTERNOON WITH HIGHER GUSTS. HOWEVER…RELATIVE HUMIDITY VALUES WILL REMAIN FROM 25 TO 35 PERCENT THIS AFTERNOON PRECLUDING RED FLAG WARNING CONDITIONS. THEREFORE…THE FIRE WEATHER WATCH HAS BEEN CANCELLED.
Here’s the forecast for Tuesday, March 27th 2012….
The National Weather Service says a Wind Advisory will be in effect from 11-am until 4-pm today (Tuesday), for parts of the KJAN listening area, along with a Fire Weather Watch, due to the danger posed by strong winds and extremely dry conditions. The Advisory and Fire Weather Watch (which is in effect from this morning through this evening), includes Audubon, Crawford, Carroll and Greene Counties in our listening area.
Strong westerly winds of 25-to 45-miles per hour, combined with low relative humidity are forecast for today. With the grasslands already being very dry, and other near dormant vegetation, there is a very real danger for quickly spreading, extremely explosive fires. All outdoor burning should be avoided.
The National Weather Service in Valley, NE has issued a “Red Flag Warning” for western Iowa’s Monona County. The warning is in effect from Noon today until 8-p.m., and means that critical fire weather conditions exist or will exist, that can create explosive fire growth potential. The Weather Service says dangerous fire weather conditions are possible this afternoon over parts of western & northwest Iowa and northeast Nebraska. Much drier air is moving into the region today, with westerly winds gusting from15-to 35-miles per hour behind a front that will be passing through. The combination of very low humidity and gusty winds will create an extremely high fire danger this afternoon.
