(a) while some say winter will be six weeks longer to the groundhog, no one really knows. one day it may be snowing, and the next it may be sunny and warm. every day is different and, while we are able to see approaching hurricanes using radar, the weather will forever go to the beat of its own drum.

(b) tropical cyclones, also known as hurricanes, cause the most damage to coastal areas because they form over the ocean before making their way to the mainland. every time a hurricane strikes land, it causes millions (sometimes billions) of dollars in damage to our coastal regions.

(c) meteorologists are able to make accurate weather forecasts using radar technology. the radar sends energy out into the atmosphere and determines what type of precipitation is in the air based on how long it takes the energy to bounce back. the heavier or thicker the precipitation, the longer it takes the energy to return.

(d) hurricanes are intense tropical storms with minimum wind speeds of 75 miles per hour. category five hurricanes can have wind speeds over 155 mph. recent trends in hurricanes indicate the intensity of these storms will continue to increase in years to come.

(e) by closely monitoring atmospheric temperatures and conditions, meteorologists are somewhat able to anticipate paths hurricanes will take, but the complexity of the storm prevents a certain prediction.

(1) hurricanes are intensely powerful storms that are only growing more intense.
(2) meteorologists can make predictions of hurricane movement, but the complex conditions make certainty impossible.
(3) modern technology utilizes energy to predict what precipitation is in the atmosphere.
(4) the coastal regions experience the most damage as a result of hurricanes.
(5) while we may know what's coming ahead of time, weather remains unpredictable.
