FNUS56 KHNX 181740 FWFHNX Fire Weather Planning Forecast for Interior Central California National Weather Service San Joaquin Valley - Hanford CA 1040 AM PDT Mon May 18 2026 ...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM PDT MONDAY FOR GUSTY WINDS AND LOW RELATIVE HUMIDITIES FOR THE SAN JOAQUIN VALLEY AND WEST HILLS ALONG THE COASTAL RANGE... .DISCUSSION... Low RH values today, along with breezy conditions in the San Joaquin Valley and the West Side Hills along the Coastal Range today. There will be threats for fast- moving grass fires in these areas. Minimum RH values will persist as well, with most areas being under 15 percent RH. As such, the Red Flag Warning continues to be in effect until 8 PM Monday. Winds are not forecasted to be as strong as they were over the weekend. A warming and drying trend will be moving into Central California later this week. The RH in the valley areas are expected to be less than 15 percent until Thursday. This leads to elevated fire weather throughout the week.
