Event Description
Lesson Description
along major roads to mark
routes for hurricane evacuation
In this lesson students make observations on Hurricane Irene and
use a data table from NOAA to graph the number and type of
tropical cyclones observed per month from 1851-2010.
(1) Introduce the event by viewing media sites/videos such as
NASA satellite videos. Ask students to describe the hurricane and
record their observations. (2) Discuss the different categories of
cyclones using the Cyclone Classification Sheet. Ask students to
predict in which month(s) they think the most Tropical Storms
occur, and ask for reasons why. (3) Pass out the NOAA data table
and the Hurricane Graph or plain graph paper. Have students plot
up the NOAA data and assess their prediction. Ask older students
for calculations based on the graph such as finding the % of tropical
storms that become hurricanes.

Each year hurricane season for the Northern Atlantic Ocean
(officially June 1st to November 30th) peaks in late August through
September when sea surface temperatures are the highest. The
term ‘tropical cyclone’ is used to describe a low pressure system
that generally forms in the tropics, is accompanied by thunderstorm activity, and rotates counterclockwise in the northern
hemisphere (NOAA). Depending on wind speeds, tropical cyclones
are classified as tropical storms, tropical depressions, and hurricanes (categorized 1-4). As the first hurricane of the 2011 season,
Hurricane Irene grew to a category 3 off the coast of Florida before
hitting the coastal regions of North Carolina to Maryland as a
category 1. In these areas it caused widespread coastal erosion &
flooding from the storm surge & wind damage. Although Irene was
downgraded to a tropical storm as it moved
north, heavy rains caused extensive flooding in
low lying regions of New York and Vermont due
to swelling creeks and reservoirs, and heavy
mountain runoff. To view and track current
tropical cyclones as they develop worldwide
