Dangerous Winds At and Near San Luis Reservoir

A continued troughing pattern over California will bring a brief influx of moisture to Sierra Nevada this afternoon. This air will interact with the terrain, leading to a slight chance (5 to 15 percent) for thunderstorms at the higher elevations between Yosemite NP and Sequoia and Kings Canyon National Park.

The Fourth of July falls during the driest part of the year. Grasses and brush are fully cured, and low humidity dries them out even further. Under these conditions, a single spark can grow into a fast-moving fire within minutes. Wind is the multiplier. Gusts push flames into fresh fuel and carry embers ahead of the fire, starting new spot fires downwind. 🎆 Fireworks rules vary by city, county, and agency, and many areas ban them entirely. Check with your local fire department or county authorities. 🔗 weather.gov/hanford
