TROPICAL STORM COSME DISCUSSION NUMBER 11
NWS NATIONAL HURRICANE CENTER MIAMI FL EP032025
800 PM MST TUE JUN 10 2025
COSME IS QUICKLY ON THE PATH TO BECOMING A REMNANT LOW. SATELLITE
IMAGES SHOW THAT THE LOW- AND MID-LEVEL CENTERS HAVE SEPARATED,
WITH THE LOW-LEVEL CIRCULATION WELL NORTHEAST OF THE MID-LEVEL ONE
NOW. DVORAK INTENSITY ESTIMATES CONTINUE TO FALL, AND THE INITIAL
INTENSITY IS SET TO 40 KT. FURTHER WEAKENING IS ANTICIPATED DUE TO
PERSISTENT SHEAR, COOL WATERS AND DRY AIR ENTRAINMENT. COSME
SHOULD TRANSITION INTO A REMNANT LOW ON WEDNESDAY MORNING AND
TOTALLY DISSIPATE IN A COUPLE OF DAYS.
THE STORM HAS TAKEN ITS LONG-AWAITED TURN, NOW MOVING SLOWLY TO THE
NORTH-NORTHEAST. COSME, OR WHAT'S LEFT OF IT, SHOULD MOVE A
LITTLE FASTER TO THE NORTH LATE WEDNESDAY AND THEN DISSIPATE INTO A
TROUGH OF LOW PRESSURE DUE TO UNFAVORABLE ENVIRONMENTAL CONDITIONS.
NO SIGNIFICANT CHANGES WERE MADE TO THE TRACK OR INTENSITY
FORECASTS.
