Reno, Nev. – Residents across western Nevada and the eastern Sierra should prepare for slow-moving afternoon thunderstorms capable of producing heavy downpours, lightning, gusty winds, and localized flooding today. The greatest risk develops during the afternoon, when monsoon moisture combines with daytime heating to fuel scattered storms.
According to the National Weather Service in Reno, 20% to 40% chances of showers and thunderstorms are expected this afternoon and evening, with the most active period occurring between noon and 7 p.m. Forecasters say localized flooding from intense rainfall is the primary concern, especially in areas that experienced heavy rain earlier this week.
The highest probability for thunderstorm development extends from the eastern Sierra into portions of western Nevada, including the Reno-Carson City corridor and nearby mountain communities. Isolated lightning is also possible farther north, although storm coverage there is expected to remain limited.
Any thunderstorm may produce brief but heavy rainfall capable of overwhelming poor drainage areas, along with gusty outflow winds and pockets of small hail. Motorists should be alert for rapidly changing road conditions, ponding water, and reduced visibility during heavier showers.
Residents planning outdoor activities should keep a close eye on the sky and move indoors immediately if thunder is heard. Those hiking or camping in canyons, burn scars, or near normally dry washes should remain aware of the potential for sudden rises in water levels.
Storm chances gradually diminish later this evening, but the National Weather Service will continue monitoring monsoonal moisture, and additional weather statements may be issued if stronger storms or flooding develop.
