The National Weather Service has declared March 27th through March
31st as Flood Safety Awareness Week in Pennsylvania.
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:
The following will describe different forms of 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
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.
