Tormenta Tropical GERT (07L Bermudas )

SATELLITE IMAGERY INDICATES THAT THE LOW PRESSURE AREA
SOUTH-SOUTHEAST OF BERMUDA HAS DEVELOPED PERSISTENT CENTRAL
CONVECTION AROUND A TIGHTLY-WOUND LOW-LEVEL CENTER.  SATELLITE
INTENSITY ESTIMATES FROM SAB AND TAFB ARE 30 KT...AND BASED ON THESE
ADVISORIES ARE INITIATED ON THE SYSTEM AS TROPICAL DEPRESSION
SEVEN.

A TROPICAL STORM WATCH IS IN EFFECT FOR...
* BERMUDA

TROPICAL DEPRESSION SEVEN HAS NOT BECOME ANY BETTER ORGANIZED SINCE
THE LAST ADVISORY

SOME STRENGTHENING OF THE DEPRESSION IS FORECAST
DURING THE NEXT 36 TO 48 HOURS AS IT REMAINS OVER RELATIVELY WARM
WATER AND IN A LOW TO MODERATE WIND SHEAR ENVIRONMENT

HOWEVER...
GIVEN THE CURRENT LACK OF ORGANIZATION OF THE SYSTEM AND DRY AIR
AROUND IT...SIGNIFICANT STRENGTHENING APPEARS UNLIKELY

Un par de dias sobre aguas tropicales, con cizalladura no superior a 15kt, aunque con mucho aire seco alrededor del sistema

SHIPS le concede el estatus de Tormenta Tropical antes de extratropicalizarse

Neuva Tormenta Tropical sobre el Atlantico.

Si no fuese Huracan, seria record?.

El aspecto mejoró comparado con el de hace algunas horas.

 

GERT Gana Fuerza

THE SFMR WINDS CORRELATE WELL WITH AN EARLIER 1324Z ASCAT
PASS THAT INDICATED SURFACE WINDS OF NEAR 40 KT IN THE SAME GENERAL
AREA OF THE CYCLONE CIRCULATION. BASED ON THE RECENT SFMR WINDS AND
EARLIER ASCAT WINDS...THE INITIAL INTENSITY IS INCREASED TO 40 KT

GERT Gana Fuerza
THE SFMR WINDS CORRELATE WELL WITH AN EARLIER 1324Z ASCAT
PASS THAT INDICATED SURFACE WINDS OF NEAR 40 KT IN THE SAME GENERAL
AREA OF THE CYCLONE CIRCULATION. BASED ON THE RECENT SFMR WINDS AND
EARLIER ASCAT WINDS...THE INITIAL INTENSITY IS INCREASED TO 40 KT

Y no solamente gana fuerza, sino que literalmente se está "merendando" al 92L Pasará justo al Este de Bermuda esta tarde-noche.

SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION

LOCATION...32.0N 63.2W
ABOUT 95 MI...155 KM ESE OF BERMUDA

MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES

THE BERMUDA WEATHER SERVICE HAS DISCONTINUED THE TROPICAL STORM
WARNING FOR BERMUDA.

Según la discursión del NHC, seguirá aumentando su fuerza en estas próximas 24 horas, pero no llegará a la Cat.1 debido entre otras causas, a lo pequeño que es el ciclón, que lo deja casi indefenso contra las intrusiones de aire seco, además de moverse por aguas de 26º C con tendencia a aguas más frías y a cizalladura creciente del SW.

GERT se situa como Tormenta Tropical mínima, a la vez que sigue diluyendose sobre las aguas cada vez mas frias del Atlántico



El NHC lo dice claramente

A CONTINUED GRADUAL WEAKENING OF GERT IS
EXPECTED AS THE STORM CROSSES THE 26C ISOTHERM LATER THIS MORNING
AND MOVES INTO STRONGER SOUTHWESTERLY SHEAR. GERT IS FORECAST TO
BECOME A POST-TROPICAL CYCLONE IN ABOUT 24 HOURS AS IT MOVES OVER
WATERS NEAR 20C
