          Branch

 

SUBJECT:  Changes to the Boundaries of Fire Weather Forecast

          Zones in Southwest Minnesota (MN) and Northwest Iowa

          (IA) Served by NWS Weather Forecast Office (WFO) Sioux

          Falls, South Dakota (SD), Effective June 16, 2016

 

Effective Thursday, June 16, 2016, at 0600 Coordinated Universal

Time (UTC), the NWS WFO in Sioux Falls (FSD), SD, will change its

current fire weather forecast zones in southwest MN (MNZ900) and

northwest IA (IAZ300 and IAZ301) to be identical to its current

public weather zones in southwest MN and northwest IA.

 

After this change, WFO FSD fire weather forecast zones in

southwest MN and northwest IA will be identical in zone name,

zone number and geographic extent to its current public weather

zones in southwest MN and northwest IA and also correspond to

county names and boundaries in southwest MN and northwest IA. 

The WFO FSD current fire weather forecast zones in South Dakota

and Nebraska will remain unchanged.

 

These changes will improve services for WFO FSD fire weather

partners by allowing WFO FSD to better align expected weather

with counties.  This is especially crucial for being able to

better time forecasted wind shifts.

 

Specifically, fire weather forecast zone MNX900 in southwest MN

will be split into multiple fire weather forecast zones identical

to current public weather zones and counties.  Fire weather

forecast zone MNZ900 will no longer exist.

 

New fire weather forecast zone numbers and names in southwest MN:

MNZ089                         Nobles

MNZ090                         Jackson

Likewise, fire weather forecast zones IAZ300 and IAZ301 in

northwest IA will be split into multiple fire weather forecast

zones identical to current public weather zones and counties. 

Fire weather forecast zones IAZ300 and IAZ301 will no longer

exist.
