What are weather temps needed to sustain a tropical depression?
      #6256 - Mon Mar 03 2003 08:37 AM

not specifically a hurricane but if someone would like to break it down i would be really appreciative..

for....say tropical disturbance, depression, storm and of course... a HURRICANE

this morning i believe Key West was around 79, what with the heat ridge over Cuba and ongoing HOT weather, should be climbing very unseasonably fast

Okay. There is pretty much a universal water temperature to support most ALL tropical cyclones in the Atlantic Basin. That temperature is the infamous 26C (80F). 80 degrees F will certainly support a disturbance, a depression/TS, and probably a cat. 1 hurricane. For a cat. 2 and up, I'd say at least 83 degrees is needed (probably warmer in most cases).

SSTA anomalies for 3/17/03:
Notice...the SSTA's are WELL above normal near the SE US. This could be a seaon-long trend and if we get any storms up the alley this year, this could be a big boost to them. That is IF these SSTA are a trend.
