TROPICAL STORM SARA DISCUSSION NUMBER 14
NWS NATIONAL HURRICANE CENTER MIAMI FL AL192024
900 PM CST SAT NOV 16 2024
SARA REMAINS A POORLY ORGANIZED TROPICAL STORM, WITH THE MOST
SIGNIFICANT BANDING FEATURES IN THE NORTHERN SEMICIRCLE WELL AWAY
FROM THE LOW-LEVEL CENTER. AIR FORCE RESERVE HURRICANE HUNTER
FLIGHT-LEVEL AND DROPSONDE DATA INDICATE THAT THE CENTRAL PRESSURE
HAS RISEN TO 1001 MB AND THE WINDS HAVE DECREASED. THE INITIAL WIND
SPEED IS SET TO 35 KT, WHICH ARE MOSTLY OCCURRING IN THE RAIN BANDS
WELL AWAY FROM THE CENTER.
AIRCRAFT FIXES INDICATE THE STORM IS MOVING SLOWLY TO THE
WEST-NORTHWEST. SARA SHOULD SLIGHTLY ACCELERATE IN THAT DIRECTION
AS MID-LEVEL RIDGING STRENGTHENS OVER THE GULF OF MEXICO THROUGH
TOMORROW. THE STORM IS EXPECTED TO MAKE LANDFALL ON SUNDAY ON THE
COAST OF BELIZE, AND VERY LITTLE CHANGE WAS MADE TO THE NHC FORECAST
WITH GUIDANCE CONSISTENT FROM THE LAST CYCLE. LITTLE CHANGE IN
INTENSITY IS EXPECTED BEFORE LANDFALL DUE TO THE DISORGANIZED NATURE
OF SARA, AND THE NEW INTENSITY FORECAST IS SLIGHTLY LOWER THAN THE
LAST ONE. THE WEAKENED CYCLONE SHOULD DISSIPATE OVER THE SOUTHERN
PORTION OF THE YUCATAN PENINSULA BY EARLY MONDAY.
THE PRIMARY HAZARD ASSOCIATED WITH SARA CONTINUES TO BE POTENTIALLY
CATASTROPHIC FLASH FLOODING, WITH SUBSTANTIAL RAINFALL CONTINUING TO
OCCUR NEAR THE NORTH COAST AND IN UPSLOPE REGIONS OF HIGHER TERRAIN
IN HONDURAS.
KEY MESSAGES:
1. THROUGH EARLY NEXT WEEK, HEAVY RAINFALL FROM TROPICAL STORM SARA
WILL CAUSE POTENTIALLY CATASTROPHIC FLASH FLOODING AND MUDSLIDES
OVER NORTHERN PORTIONS OF HONDURAS.
2. ELSEWHERE ACROSS BELIZE, EL SALVADOR, EASTERN GUATEMALA, WESTERN
NICARAGUA, AND THE MEXICAN STATE OF QUINTANA ROO, HEAVY RAINFALL
