| The GFS forecast model is run four times per day. It is one of the major models the weather agencies use to project weather patterns as well as hurricane track. The reliability of the forecast decreases the further out in time it goes. The L's and the H's on the maps are the highs and the lows. Low pressure systems can turn into tropical storms and hurricanes if the conditions are right. Some of the factors that are required for storm formation are warm seas (SSTs), low windshear, and moist air. A low must have a warm core before it can be tropical. The black lines represent pressure, the lower the pressure the stronger the storms. |
