WILLIAMS — A moist airmass over Arizona with the potential of heavy rain producing thunderstorm complexes caused the National Weather service to issue a flash flood watch in portions of east central and west central Arizona. The areas affected are northern Gila County, Oak Creek and Sycamore Canyons, Yavapai County Mountains, and Yavapai County Valleys and Basins. Rainfall rates can result in strong, rapidly rising water in area washes, which may create hazardous conditions at low water crossings. . Localized rainfall amounts could exceed 1 inch in less than an hour, with storm total rainfall possibly above 3 inches. The Flash Flood Watch runs from September 23 at 3:19AM MST until September 24 at 5:00AM MST.

NOAA warns against crossing flooded roads and low-laying areas. No matter how powerful your vehicle, it does not take much water flow to carry it downstream.

In Williams there is an 40% chance of thunderstorms raising to 80% tonight. Thunderstorms are likely through Sunday.
