Public Information Statement

Statement as of 6:01 AM EDT on April 29, 2016


... This is severe weather awareness week...

This statement covers flash floods.

Since 1996... flash floods have accounted for over 10 deaths and more
than 125 million dollars in property damage across the tri state
area.

Flash floods can occur anywhere from within a few minutes to a few
hours of excessive rainfall. The two key elements contributing to
flash flooding are rainfall intensity and duration.

Slow moving thunderstorms moving over the same area can produce
rainfall rates in excess of 1 to 2 inches per hour for several
hours. These storms... which climatologically occur from Spring
through fall... can produce flash flooding of streets... poor drainage
areas... small streams and rivers.

Never drive through a flooded roadway. Turn around... do not drown.
It takes only 6 inches of running water to knock down an adult... and
just 12 inches of running water to carry away a small car. 2 feet of
rushing water can carry away most vehicles. It is never safe to
drive or walk into flood waters.

When there is a potential for flooding beyond 48 hours... our
National Weather Service office on Long Island NY will provide this
information in our hazardous weather outlook text product.

Flood watches are issued by our NWS office when there is a potential
for any type of flooding... within 48 hours.

Flash flood warnings will be issued when any type of flooding...
except tidal flooding... will create an immediate threat to life and
property within 6 hours. Last year... we correctly forecast 95
percent of 40 flash flood events with an average lead time of 59
minutes. Our office uses a combination of weather radar... rain gages
and volunteer Skywarn spotter observations to issue warnings.

The final statement will cover a review of topics presented during
this week.
