Public Information Statement
National Weather Service Taunton MA
1128 AM EDT Wed Mar 15 2017

March 13 through March 17 is Flood Safety Awareness week. The
National Weather Service in Taunton will feature information
about a different flood topic each day during today through

Today`s topic - Floods Hazards

a flood is defined as any high flow, overflow, or inundation
of water that causes or threatens damage. Flooding can occur with
prolonged rainfall over several days, intense rainfall over a
short period of time, or when water from an existing source
moves too quickly (i.e. snowmelt, dam break, etc...). Brief
descriptions of the various types of flooding you may experience
are found below. More information about these flood hazards can
be found on the NWS flood safety website at

Flash Flooding - Flash flooding is a rapid and extreme flow of
high water into a normally dry area, or a rapid water level rise
in a stream or creek above a predetermined flood level,
occurring in a short duration (i.e. intense rainfall,
dam failure, ice jam). In southern New England, urban flash
flooding is a concern due to the potential for heavy rains to
collect rapidly in poor drainage areas or overwhelming drainage

River Flooding - River flooding occurs when rivers rise and
overflow their banks, inundating areas that are normally dry.

Tropical Systems and Coastal Flooding - At any time of year, a
storm from over the ocean can bring heavy precipitation to the
U.S. coasts. Whether such a storm is tropical or not, prolonged
periods of heavy precipitation can cause freshwater flooding in
coastal areas, as well as further inland as the storm moves
onshore. In addition to the freshwater flood threat, tropical
cyclones and nor`easters can bring the threat of storm surge
related coastal flooding.

Snowmelt - Flooding due to snowmelt most often occurs in the
spring when higher temperatures quickly melt the snow. The water
runs off the still partially frozen or already saturated ground
into nearby streams and rivers, causing them to rapidly rise
and sometimes overflow their banks.

Ice and Debris Jams - A backup of water into surrounding areas
can occur when a river or stream is blocked by a build-up of ice
or other debris.

Dam Break and Levee Failure - A break or failure can occur with
little to no warning. Most often they are caused by water
overtopping the structure, excessive seepage through the
surrounding ground, or a structural failure.

Understanding the different flood hazards and knowing the actions
to take before, during, and afterwards can help you protect
your life, the lives of your loved ones, and your property.
