What to do
Move to higher ground if you are in a low-lying area, near a creek or wash, or in an underpass. Do not wait to see water rise.
Never drive around barricades or into flooded roads. The National Weather Service says just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
Expect muddy, impassable dirt roads and possible flooding of paved roads and underpasses. Avoid creeks, washes and recreation areas named in the warning, such as Watson Lake Park and Acker Park.
Stay tuned to National Weather Service updates until the warning ends or is cancelled.
