Special Weather Statement
Southwest winds gusting up to 30 mph, unseasonably warm
temperatures, low relative humidities, and dry vegetation will
result in a heightened risk of grass, brush, and field fires this
afternoon.
Any fires that ignite may become difficult to control due to the
strong winds and dry conditions. Outdoor burning is strongly
discouraged. Please heed any local burn bans. Take care to prevent
the start of accidental fires when handling cigarettes or
operating vehicles and farm equipment around dry vegetation or
crops.
Additionally, the gusty winds may cause dust from harvesting
activities to be blown around, resulting in localized sharp
visibility reductions. Motorists are advised to use caution when
driving near farmland, particularly on east-west roads in open
areas.
