The flash flood warning poses a significant risk to residents and commuters in Fresno County, particularly in the Five Points area and along Highway 99. Heavy rain and thunderstorms could lead to localized flooding, making roads hazardous. In Selma, intense rainfall has already caused flooding in some neighborhoods, with vehicles navigating through standing water. Wind gusts of up to 40 mph and pea-sized hail may also cause additional hazards, such as downed power lines and property damage. Drivers are urged to exercise caution and avoid flooded areas.
