Effective: Sun March 29, 2026, 12:17 AM
Expires: Sun March 29, 2026, 6:00 PM
Dry and breezy conditions expected today. The combination of afternoon RH values around 30 to 40 percent and a southwesterly flow increasing to 20 to 25 mph gusts will result in an elevated risk of fire spread. Use caution when handling any potential ignition sources, including machinery, cigarettes and matches. Any fires that ignite will have the potential to spread quickly. The forecast considers meteorological, fuel and land conditions and has been developed in coordination with state fire and land management officials.
