City Department of Emergency Management officials are warning residents to stay off the roads as heavy rains and flooding hit Oahu early this morning.

“Stay off the roads unless travel absolutely needed. If you have a flood related emergency call 911,” they said after 4:30 a.m. Sunday.

They issued the following advice to residents:

When a flash flood WARNING is issued for your area, or the moment you realize that a flash flood is imminent, act quickly to save yourself. You may have only SECONDS! Go to higher ground or climb to safety!

>> Get out of areas subject to flooding. This includes dips, low spots, washes, etc.

>> Avoid already flooded and high velocity flow areas. Do not attempt to cross flowing streams.

>> If driving, be aware that the road bed may not be intact under flood waters. Turn around and go another way. NEVER drive through flooded roadways!

>> If the vehicle stalls, leave it immediately and seek higher ground. Rapidly rising water may engulf the vehicle and its occupants and sweep them away. Remember, it’s better to be wet than dead!

>> Be especially cautious at night when it is harder to recognize flood dangers.

>> Do not camp or park your vehicle along streams and washes, particularly during threatening conditions.

When you receive a FLOOD WARNING:

>> If advised to evacuate, do so immediately.

>> Move to a safe area before access is cut off by flood water.

>> Continue monitoring NOAA Weather Radio, television, or emergency broadcast station for information.

During the flood:

>> Avoid areas subject to sudden flooding.

>> If you come upon a flowing stream where water is above your ankles, STOP! Turn around and go another way.

>> Do not attempt to drive over a flooded road. The depth of water is not always obvious. The road bed may be washed out under the water, and you could be stranded or trapped.

>> Children should NEVER play around high water, storm drains or viaducts.

If you have a flood related emergency call 9-1-1 immediately.
