Public Information Statement
National Weather Service Binghamton NY
800 AM EDT Wed Mar 15 2017

Tthe National Weather Service in Binghamton New York, has declared
March 12th through March 18th as Flood Safety Awareness Week.

The National Weather Service in Binghamton will feature information
about a different flood topic each day during the awareness week.

Today`s topic: Flood Hazards

Flooding is a coast-to-coast threat to the United States and its
territories during every month of the year. Flooding typically
occurs when prolonged rain occurs over several days, or when intense
rain falls over a short period of time, or when ice or debris jam
causes a river or a stream to overflow onto the surrounding area.
Flooding can also result in the failure of a water controled
structure, such as a levee or dam. The most common form of flooding
is rain and/or snowmelt that accumulates faster than the soil can
absorb it, or the rivers can carry it away. Approximately
seventy-five percent of all Presidential Disaster declarations are
associated with flooding. More information about these flood hazards
can be found on the NWS flood safety website at:
www.floodsafety.noaa.gov.

The following will describe different forms of flooding:

Flash Flooding:
Flash flooding are floods that happen in a flash! This type of flood
generally develops within six hours of the immediate cause. Causes
can include heavy rain, ice, debris jams, levee or dam failures.
Flash floods are rapid rises in water level in streams or creeks
above a predetermined flood level.

Tropical systems and coastal flooding:
Coastal flooding generally occurs with a land-falling or near-land
system such as a tropical storm or hurricane. Storm surge and large
waves produced by hurricanes pose the greatest threat to life and
property along the coast. Tropical systems can bring copious amounts
of precipitation onshore. Tropical systems are not the only type of
storms that can cause coastal inundation and storm surge. All times
of the year storms can impact U.S. Coastal regions. Pacific storm
systems and Nor`easters can create devastating floods as well.

River flooding:
River flooding occurs when river levels rise and overflow their
banks or the edges of their main channel to inundate areas that are
normally dry. River flooding can be caused by heavy rainfall, dam
failures, rapid snowmelt and ice jams. River flooding is classified
as Minor, Moderate, or Major based on pre-determined water height
thresholds and impacts near the river.

The three stages of river flooding are:
Minor: low-lying areas adjacent to the stream or river; mainly rural
areas, farmland and secondary roadways.

Moderate: Water levels rise high enough to impact homes and
businesses near the river. Some evacuations may be needed.

Major: Extensive rural and/or urban flooding is expected. Usually
with significant water depths and destruction to property in, and
near the floodway.

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