Hurricane Tracking and Forecasting

The path of a storm is tracked using satellite photos and RADAR. You can plot the latitude and longitude of the center of the storm as the hurricane travels (lines of latitude run east and west; lines of longitude run north and south). The coordinates of a storm's location look like (20ºN, 75ºW), where the first coordinate is the current latitude of the storm and the second coordinate is the longitude.

How to Track a Hurricane:

To plot each location of the storm over time, do the following:

1. Determine the latitude of the storm, the first coordinate in the pair, and locate it on the map (usually followed by an N or S). Latitude measures how far north or south a location is from the Equator (on a map, lines of latitude run east and west).
2. Determine the longitude, the second coordinate in the pair (usually followed by a W or E), and locate it on the map. Longitude measures how far east or west a location is from the Prime Meridian (on a map, lines of longitude run north and south).
3. Draw a (for a hurricane) or a (for a tropical storm) on the weather map.
4. Repeat steps 1 to 3 using the next tracked location of the storm.

To plot a hurricane located at the point (20ºN, 75ºW), do the following. First locate the 20ºN latitude line on the map (it is highlighted in red). Then locate the 75ºW longitude line on the map (it is highlighted in green).

The storm's location is the intersection of these two lines. Plot the storm's location on the map at that point (over eastern Cuba in this example).
