Tropical Storm Nicole - September 28-29, 2010

As Tropical Storm Matthew moved through Central America into southeast Mexico, the monsoon trough
from the eastern Pacific moved northeastward into the northwest Caribbean sea.  While Matthew was weakening
across the Isthmus of Tehuantepec, a broad monsoon depression formed within the monsoon trough just offshore
Belize and Honduras on September 25th, southeast of the base of a deep trough located over the Midwest.  The low
slowly deepened as it moved northeast, and developed a well-defined circulation center on the 28th, when it was
classified as a tropical depression.  The system slowly organized, becoming a tropical storm as it was crossing Cuba
on the 29th.  Later that morning, the cyclone lost its well-defined circulation center, and the remnant low moved
north-northeast to northeast near the coast of Florida and the northwest Bahamas before becoming absorbed by a
new non-frontal cyclone to its north off of northeast Florida.  Below are the storm total rainfall maps for Nicole for the
Eastern United States, which were produced using data from the National Weather Service River Forecast Centers,
the Key West Weather Forecast Office, and CoCoRAHS.  The heavy rains in east-central Florida developed north of
Nicole when a disturbance aloft tapped its moisture, and could be considered a predecesor rainfall event (PRE).
