A red flag warning is in effect for leeward areas due to gusty winds and low humidity, the National Weather Service said Sunday.
“Provided the lack of any significant rainfall through the summer months, fuels have become very dry across portions of the state,” forecasters said. “These dry conditions combined with breezy trades and relative humidities dipping below 45 percent through the afternoon hours will support extreme fire behavior through Monday.”
The warning covers leeward portions of all Hawaiian Islands.
Trade winds of 20 to 25 mph with gusts reaching 35 mph are forecast with humidity expected to be between 35% and 45% during the afternoon.
Forecasters cautioned that any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
