  <div class="eI1">Description:</div>
  <div class="eI2">
The precipitation map - updated every 6 hours - shows the modeled precipitation in mm.
The precipitation areas are encircled 
by isohyets - lines with equal amounts of precipitation. However, modeling precipitation is 
still not very reliable. If you compare the modeled results with observed values you will 
realize that the model is nothing better than a first order approach. Yet this chart is of some 
use for forecasters.<br>
Note: Based on international convention meteorologists use the metric system. 100 mm of 
precipitation is equivalent to roughly 4 inches.
