FIRE WEATHER
WATCH A Fire Weather Watch is used to advise of the possible
development of a red flag event in the near future. Usually fire danger is in the very high to extreme category. A Fire Weather
Watch will normally be issued 12 to 24 hours in advance of the expected onset of severe fire weather conditions. The watch
will be issued via an RFW product (i.e. RFWOKX). The product will contain a headline and the basis for the watch issuance.
Fire Weather Watch information will be included in the affected areas of the daily routine Fire Weather Forecast. A Fire Weather
Watch will be canceled via an RFW if subsequent information indicates that the conditions are no longer expected to develop.

daily routine Fire Weather Forecast. A Red Flag Warning will be canceled via an RFW if subsequent information indicates that
