Tropical Storm ERICK


ZCZC MIATCDEP5 ALL
TTAA00 KNHC DDHHMM
 
TROPICAL STORM ERICK DISCUSSION NUMBER  14
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP052013
200 PM PDT SUN JUL 07 2013
 
ALTHOUGH THE CIRCULATION OF ERICK REMAINS VIGOROUS...THE CYCLONE
HAS LOST MOST OF ITS THUNDERSTORM ACTIVITY THIS AFTERNOON.
RECENTLY...HOWEVER...DEEP CONVECTION HAS REDEVELOPED OVER THE
EASTERN SEMICIRCLE.  THE INITIAL WIND SPEED IS LOWERED TO 50 KT IN
ACCORDANCE WITH THE VARIOUS SATELLITE ESTIMATES.  THE NEW NHC
INTENSITY FORECAST CONTINUES THE TREND OF THE PREVIOUS ONE...
SHOWING A STEADY DECREASE IN STRENGTH DUE TO COOLING WATERS AND
ENTRAINMENT OF MORE STABLE AIR.  ERICK SHOULD BECOME A REMNANT LOW
IN 36 TO 48 HOURS WHEN IT MOVES OVER EVEN COOLER WATERS.
 
THE CYCLONE HAS TURNED TOWARD THE WEST-NORTHWEST TODAY...WITH AN
INITIAL MOTION OF 300/9.  A MOTION BETWEEN WEST-NORTHWEST AND
NORTHWEST IS FORECAST DUE TO A STRONG RIDGE OVER WESTERN NORTH
AMERICA.  THE MODEL GUIDANCE IS IN REASONABLE AGREEMENT ON THIS
SCENARIO...ALTHOUGH THERE HAS BEEN A SMALL SOUTHWARD SHIFT OF THE
MODELS ON THIS ADVISORY CYCLE.  THE OFFICIAL FORECAST REFLECTS THIS
TREND BY BEING JUST SOUTH OF THE PREVIOUS ONE THROUGH 36 HOURS. 
AS ERICK BECOMES A SHALLOW REMNANT LOW...IT SHOULD TAKE A MORE
WESTWARD TURN AND SLOW UNDER THE INFLUENCE OF A WEAK EASTERN
PACIFIC LOW-LEVEL RIDGE.
