I found this information on a Utah website. But I think the information may be applicable to our situation here in Brooklyn.

If the waters rise, there are definite things to do and not to do.

DO:
– Have a battery-powered radio tuned to a local station and follow all emergency instructions.

– Have a 72-hour kit with fresh water and food and keep it in an easy to locate spot in the event of evacuation.

– Secure all outdoor equipment, furniture and other movable objects that might be swept away.

– If directed to evacuate and time permits, turn off all utilities – gas, water and electricity – at the main switch or valve.

DO NOT:
– Walk through flood waters. One foot of flood waters can knock you off of your feet . The water can often be contaminated by sewage and flood-related chemical spills.

– Drive around barricades. Two feet of water is enough to float an automobile. Flood waters can conceal places where roadways or bridges have been washed out.

REMEMBER:
– Any low-lying area has the potential to flood. Inundation flooding may occur when the amount of rainfall and runoff exceeds a storm water system’s capability to remove it.

WHAT DOES IT MEAN:
– A flood watch means that rainfall is or is predicted to be heavy enough to cause rivers to overflow their banks.
– A flood warning means flooding is either occurring or likely to occur soon.
– A flash flood watch means heavy rains are occurring or are predicted and may cause sudden flash flooding in specific areas.
– A flash flood warning means flash flooding is occurring or imminent at designated areas.
