SUBJECT:  NWS Weather Forecast Office Charleston, SC,

          Will Split the Fire Weather Forecast Zone for Berkeley

          County, SC, Effective March 19, 2012


Effective Monday, March 19, 2012, at 2 pm EDT, 1800 Coordinated Universal Time (UTC), the NWS Weather Forecast Office (WFO) in Charleston (CHS), SC, will split its fire weather forecast zone for Berkeley County (SCZ045), SC, into two fire weather forecast zones: Inland Berkeley (SCZ045) and Tidal Berkeley (SCZ052).  Splitting Berkeley County into two fire weather forecast zones will allow WFO CHS to provide more specific fire weather forecast and warning services.


Berkeley fire weather forecast zone (SCZ045) will retain its zone number because the fire weather climatology of the zone will not change significantly as a result of the split. This zone will, however, be given a new fire weather zone name, Inland Berkeley, to better identify its geographic extent. Tidal Berkeley fire weather forecast zone (SCZ052) will have a new zone name and number to account for its differing climatology.
