Strong La Nina

Conditions were exactly the opposite during the dry season of 1999-2000 when strong La Nina conditions prevailed. The map below shows well below normal rainfall (blue) for Florida and the southeast states for the month of February 1999 when the storm track moved well to the north of the state. Note the excessive rainfall in the west also shifted northward out of California into the Pacific Northwest.

The graph below shows accumulated dry season rainfall (green) versus normal for the Florida grid from 1 November 1999 to 30 April 2000 during strong La Nina conditions. The dry season began with below normal rainfall and the rainfall deficit continued to build throughout the dry season, exactly the opposite of the strong EL Nino case.
