...Critical Fire Weather through Monday... A cold frontal passage on Sunday morning will be followed on Sunday afternoon by northerly winds gusting around 25 mph, and RH will be dropping in the afternoon as a drier air mass arrives. Lingering cloud cover will be the main inhibitor to active fire behavior on Sunday, but critical conditions remain possible Sunday afternoon. With dry air continuing to filter in on Sunday night, there will be poor nighttime humidity recovery. On Monday, the heart of the dry air mass will be in place, with minimum relative humidities commonly in the 15-20 percent range. Sustained northeast winds will be near 10 to 15 mph and support extremely high dispersion. Full sunshine, seasonably warm late April temperatures, and ongoing drought will all contribute to a critical fire environment. A Fire Weather Watch remains in effect for Monday where winds are currently forecast to touch 15 mph. The watch could be expanded in later forecast updates. * AFFECTED AREA...Florida fire weather zones 010, 011, 012, 014, 015, 028, 029, 034, 112, 114, 115, 118, 127, 128, and 134. Georgia fire weather zones 143 and 155. * WIND...Northeast near 15 mph, with gusts near 25 mph. * HUMIDITY...15-20 percent, following poor humidity recovery on Sunday night. * IMPACTS...Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.

A Fire Weather Watch means that critical fire weather conditions are forecast to occur. Listen for later forecasts and possible Red Flag Warnings.
