That’s Noah or NOAA? The National Weather service has a feature specifically to address the particular issues related to weather and ground or oceanic waters, called The National Oceanic Atmospheric Administration. This group keeps an eye on waters on the ground that may threaten the public. http://www.noaawatch.gov/floods.php has a listing of current at risk areas, and it looks a good bit like the Doppler map does for storms.
The two versions of flooding that most likely effect Oklahoman http://www.noaawatch.gov/themes/flooding.php
Flash floods: Flash floods are typically caused by short, intense rainfall over areas as small as a city to larger than a state. Flash flooding risks can occur well away from rivers and streams. Water pools in low spots such as underpasses and basements because rain falls faster than the ground can absorb it. Year in and year out, flash floods take more lives than any other type of flooding – most flood fatalities involve motorists. The cumulative effect of widespread, prolonged flash flooding can lead to flooding of smaller streams and, if enough rain falls, major river systems.
Riverine flooding: When runoff from widespread rain events flows into rivers and streams faster than the water moves downstream, excess water causes flooding along these waterways. Once a river reaches flood stage, flood severity categories are used by the NWS to communicate the expected flood impact.
People who live near coastal areas are more likely to have specific mass community plans to deal with a flood. http://www.floodsmart.gov/toolkits/spanish/downloads/english/flood-prepa… FEMA suggests that things like buying flood insurance for property and personal items is a great start. The pamphlet identifies some other steps to take.
Here is a family handout for flood education. http://www.nws.noaa.gov/om/brochures/owlie/Owlie-floods.pdf
Probably the most common advice is to a) watch the weather reports for flash flooding conditions this would include brief heavy rains. b) do not drive into standing or moving water c) learn which streets might be inclined to flood in your area, and avoid using those streets when there is a possibility of slow or poor drainage d) develop a safety plan or move yourself/family from a low lying area if you have experienced flooding in the past and flood conditions are announced.
Many people consider Oklahoma tornadoes to be a big problem, but the presence and frequency of flooding is actually greater than most think. Be alert, drive safe, keep tuned to local weather.
