TROPICAL DEPRESSION MARTY DISCUSSION NUMBER  14
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP162009
800 AM PDT SAT SEP 19 2009
 
THERE HAS NOT BEEN MUCH CONVECTION NEAR THE EXPOSED CENTER OF MARTY
DURING THE PAST FEW HOURS. AN ASCAT PASS AT 0522 UTC SHOWED WINDS
OF ABOUT 25 KT...AND THAT VALUE WILL BE USED AS THE INITIAL
INTENSITY. COOLER WATERS AND STRONG SHEAR SHOULD PROMOTE FURTHER
WEAKENING AND A TRANSITION TO A REMNANT LOW LATER TODAY.  MARTY IS
CURRENTLY MOVING WEST-NORTHWEST BUT A WESTWARD TURN IS ANTICIPATED
BY THIS EVENING DUE TO LOW-LEVEL RIDGING OVER THE EASTERN PACIFIC. 
THE OFFICIAL FORECAST IS BASICALLY AN EXTENSION OF THE PREVIOUS
FORECAST...WITH THE REMNANT LOW LIKELY DISSIPATING SHORTLY AFTER 48
HOURS.
