foothills west of Reno and Carson City.

rainfall rates of 0.25 to 0.50 inches per hour likely. This
intense period of heavy rain will lead to minor flooding near
creeks, streams and poorly drained urban areas.

and ponding of water on roads. Motorists are urged to slow down

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses
as well as other drainage areas and low lying spots.
