Description

...RED FLAG WARNING IN EFFECT THROUGH THIS AFTERNOON FOR GUSTY WINDS AND LOW HUMIDITY... .A dry and locally windy trade wind flow will produce critical fire weather conditions today, and possibly into Saturday. Winds will be strongest over and downwind of terrain. * AFFECTED AREA...Leeward portions of all Hawaiian Islands and interior sections of the Big Island. * TIMING...Until 6 PM HST this evening. * WINDS...East 15 to 30 mph with gusts up to 40 mph on Oahu and Kauai, and gusts up to 50 mph in Maui County and on the Big Island. * RELATIVE HUMIDITY...Lowering to 35 to 45 percent in the afternoon hours. * IMPACTS...A combination of strong winds, low relative humidity, and dry fuels can contribute to extreme fire behavior. Any fires that develop will likely spread rapidly. A Red Flag Warning does not predict new fire starts.

Instruction

Outdoor burning is not recommended. Heat from vehicle exhaust systems can ignite dry grass. Park cars on areas that are paved or where vegetation is trimmed and cleared. High winds contribute to wildfire hazard. Delay activities that could throw off sparks until the wind dies down. A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior. A Red Flag Warning does not predict new fire starts.
