Monsoonal moisture continues to stream northward into central and northern Nevada with anomalously high atmospheric moisture content for this time of year. This will promote heavy rainfall rates and runoff potential in stronger showers and thunderstorms this afternoon and evening. * WHAT...Flash flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of eastern, north central, northeast, and south central Nevada, including the following areas, in eastern Nevada, White Pine. In north central Nevada, Northern Lander and Northern Eureka and Southern Lander and Southern Eureka.
