Tropical Atlantic Remains Unusually Cool; Hurricane Development Hindered

Posted: Updated:

NOAA satellite and buoy data indicates that the deep tropical Atlantic, normally a late summer and early fall principal breeding ground for tropical cyclones, remains unusually cool.  This has been the persistent pattern for several months and was originally projected to fade as the summer progressed, but the warm up has not yet occurred.  The graphic shown depicts temperature departures by color code, with blues cooler than normal and reds warmer than normal.  In addition to the cooler sea surface temperatures, Saharan dust and increasing westerly wind shear (associated with an emerging el nino pattern) will continue to inhibit tropical storm and hurricane development.  Remember, however, that it only takes one storm where you live to make it an active year.
