Mariposa County Oak Fire Updates for Sunday, July 31, 2022
July 31, 2022 - Five states reported new large fires yesterday: California, Montana, Oklahoma, Oregon and Texas. Nationally, 54 large fires and complexes have burned 1,547,207 acres. More than 
8,700 wildland firefighters and support personnel are assigned to incidents. Five Type 1 incident management teams (IMT), six Type 2 IMTs and one complex IMT are assigned to large fires in eight geographic areas.
The potential for lightning followed by a heat wave across the northern half of the West could increase the potential for significant fire activity. Hot and dry conditions with very little rain will continue across the Plains, Texas, Southeast and Midwest. For more information, visit the Predictive Services fuels and fire danger summary, fire weather and potential briefing, and the seven-day significant fire potential outlook.
While you enjoy your precious public forests and rangelands, it is critical for you to be fire safe. Check for local fire restrictions and abide by them. Have spark arresters on equipment and vehicles like chain saws, motorcycles and all-terrain vehicles. Exhaust systems on any vehicle can easily ignite vegetation, so drive and park in designated areas keeping off and away from dry grass and brush. Please do your part to prevent wildfires and recreate responsibly.
Very hot, including record setting, temperatures are expected again across the Pacific Northwest and into portions of the northern Great Basin, northern Rockies, and northern California. Isolated to scattered mixed wet and dry thunderstorms are likely across northern California, western and northern Oregon, and possibly into northeast Oregon and central Idaho. Near drier thunderstorms, pyrocumulonimbus development is possible on active large wildfires. Isolated thunderstorms are possible in central California, including along the coast. Scattered to numerous monsoonal thunderstorms are expected across the greater Four Corners region, southern California, and much of Nevada, although drier thunderstorms are likely in portions of northern Nevada. Coverage of hot, dry, and unstable conditions will increase across Texas and portions of Oklahoma. Thunderstorms are expected from eastern Oklahoma through the southern Appalachians, with less coverage just inland from the Gulf Coast and in Florida. Stronger to severe thunderstorms are likely in portions of Minnesota and the western Great Lakes. Isolated thunderstorms are possible in the Alaskan Interior.
