Annotate (label) these photographs of Hurricane Katrina to show the primary and secondary effects (also think about what you
can’t see, for example effect on the economy)

The Path of the Storm
Landfall
New Orleans and Levee repairs
The southern Gulf Coast of the United States
bore the brunt of Katrina. Officials believe
several thousand people may be dead.
Thousands of people have been made homeless
in New Orleans. Some 80% of the city is flooded
and there has been widespread looting. A
complete evacuation of the city has been
ordered.
The death toll in Mississippi is at least 100, while
hundreds of houses and businesses - including
dozens of waterfront casinos - have been
destroyed. About a million homes are without
electricity.
In Biloxi, one of the most seriously damaged
towns, many casinos and businesses have been
looted. The town of Gulfport has also been
heavily damaged.
About 400,000 homes and businesses are
without power in Alabama, while parts of the city
of Mobile have been badly flooded.
In southern Florida, where the hurricane passed
through on 25-26 August, 100,000 homes and
businesses are without electricity.

future?
9. How could climate change influence the pattern of tropical storms in the future?
Page 78-79
Make 2 spider diagrams –
How could Global Warming
cause more frequent and
intense Tropical Storms?
How could El Nino influence
climate?
