If outdoors, consider seeking shelter inside a building. 

Torrential rainfall is also occurring with this storm and may lead to

small creeks and streams, and ponding of water in urban areas,
highways, streets and underpasses, as well as other poor drainage
areas and low lying spots.

Do not drive your vehicle into areas where the water covers the
roadway. The water depth may be too great to allow your car to cross
