Floods are the most common and wide spread of all natural hazards. Some floods develop over a period of days, but flash floods can result in raging waters in just a few minutes. Flash floods carry a deadly cargo of rocks, mud and other debris, and occur without any visible sign of rainfall. Mudslides are another danger created by flooding.
Be aware of floods hazards, especially if you live in a low lying area, near water, or downstream from a dam. Even very small streams, gullies, creeks, culverts, dry sea beds or low-lying ground that appear harmless in dry weather can flood. Every state is at risk from this hazard.
What To Do Before A Flood
- Know the terms used to describe flooding:
- Ask your local emergency management office whether your property is in a flood prone area. Learn the elevation level of your property. This will help you know how your property will be affected when flood levels are forecasted. Ask how you can protect your home from flooding.
- Identify dams and determine whether they pose a hazard.
- Ask your local emergency manager about official flood warning signals. Learn what to do when you hear them. Purchase a NOAA Weather Radio with battery backup and a tone-alert feature which automatically alerts you when a watch or warning is issued.
- Be prepared to evacuate. Learn your community's flood evacuation routes and where to find high ground.
- Talk to your family about flooding. Plan a place to meet your family in case you are separated from one another in a disaster and cannot return home. Choose an out of state contract for every one to call to say they are okay. In some emergencies, calling out of state is possible even when local phone lines are down.
- Determine how you would care for family members who may live elsewhere and might need your flood. Determine any special needs your neighbors might have.

::: Tsunamis :::
Tsunami (pronounced soo-na-mee), sometimes called a tidal wave, is actually a series of enormous waves created by an underwater disturbance or earthquake. Tsunamis can move hundreds of miles per hour in the open ocean and smash into land with waves more than 100 feet high.
All tsunamis are potentially dangerous, even though they may not damage every coastline they strike. Some waves in the series are less hazardous than others.
How to prepare for a tsunami:
What to do during a hurricane threat:
Hurricanes are tropical cyclones with torrential rains and sustained winds of 74 miles per hour or greater, which blow in a counter-clockwise direction around a center (eye).
Hurricane winds can exceed 155 miles per hour and severely effect areas hundreds of miles inland.
Hurricanes are classified into the five categories below, based on their wind speeds, central pressure and damage potential:
