Tropical Storm LANE


ZCZC MIATCDEP2 ALL
TTAA00 KNHC DDHHMM
 
TROPICAL STORM LANE DISCUSSION NUMBER   6
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP122012
200 PM PDT SUN SEP 16 2012
 
SATELLITE IMAGERY DURING THE PAST FEW HOURS SHOWS LITTLE CHANGE IN
THE CLOUD PATTERN OF LANE...WITH THE EXCEPTION OF A DEVELOPING
SMALL DENSE OVERCAST.  THEREFORE...THE INITIAL INTENSITY IS HELD AT
55 KT...AND COINCIDES WITH THE SUBJECTIVE SATELLITE INTENSITY
ESTIMATES.  THERE STILL APPEARS TO BE A SMALL WINDOW OF
OPPORTUNITY FOR LANE TO BECOME A HURRICANE...AND THIS SHOULD OCCUR
WITHIN THE NEXT 24 HOURS.  THROUGH THE REMAINING PORTION OF THE
FORECAST...INCREASING SOUTHWESTERLY SHEAR...A MORE STABLE
ATMOSPHERE...AND COOLER SEA SURFACE TEMPERATURES SHOULD INDUCE
RAPID WEAKENING.  THE OFFICIAL NHC FORECAST IS A COMPROMISE OF THE
SHIPS MODEL AND THE LGEM...AND IS A LITTLE HIGHER THAN THE IVCN
CONSENSUS.
 
THE INITIAL MOTION ESTIMATE IS 315/7. LANE IS MOVING WITHIN THE
MID-LEVEL SOUTHEASTERLY FLOW OF THE SUBTROPICAL RIDGE STRETCHING
WESTWARD OVER CENTRAL MEXICO AND THE EXTREME EASTERN PACIFIC. THE
LARGE-SCALE MODELS INDICATE THAT THE CYCLONE SHOULD CONTINUE ON
THIS GENERAL MOTION THROUGH THE NEXT 48 HOURS.  AFTERWARD...LANE
IS FORECAST TO TURN TOWARD THE WEST-NORTHWEST AND WEST AS A REMNANT
LOW IN RESPONSE TO THE LOW-LEVEL EASTERLY STEERING FLOW.  THE NHC
FORECAST TRACK IS BASICALLY AN UPDATE OF THE PREVIOUS ONE...AND IS
BASED ON THE TVCE MULTI-MODEL CONSENSUS.
