rain continues through the morning hours. Flash flooding is
ongoing and is expected to continue through the morning hours.
HAZARD...Flash flooding caused by heavy rain.
SOURCE...Reports of roads washed out with upwards of 4 feet of
standing water, flooded underpasses, and other
significant flooding from an Off-Duty National Weather
Service Meteorologist, trained weather spotters, and
law enforcement.
IMPACT...Flash flooding of small creeks and streams, urban
areas, highways, streets and underpasses as well as
other poor drainage and low-lying areas.

Stay away or be swept away. River banks and culverts can become
unstable and unsafe.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.
