Official information and local resources
Be especially cautious at night when it is harder to recognize the dangers of flooding. Remain alert for flooding even in locations not receiving rain. Washes, streams, and rivers can become raging killer currents in a matter of minutes, even from distant rainfall. Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks.
