BULLETIN
TROPICAL STORM FERNANDA ADVISORY NUMBER   4
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP062011
800 AM PDT TUE AUG 16 2011

...THE SIXTH TROPICAL STORM OF THE SEASON FORMS WELL AWAY FROM
LAND...


SUMMARY OF 800 AM PDT...1500 UTC...INFORMATION
----------------------------------------------
LOCATION...12.3N 134.5W
ABOUT 1775 MI...2855 KM WSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA
MAXIMUM SUSTAINED WINDS...45 MPH...40KT...75 KM/H
PRESENT MOVEMENT...W OR 270 DEGREES AT 8 MPH...13 KM/H
MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES


THE INTENSITY FORECAST FOR FERNANDA IS PROBLEMATIC.  WHILE SHEAR IS
FORECAST TO BE LIGHT FOR THE NEXT COUPLE OF DAYS...THE
THERMODYNAMIC ENVIRONMENT IS MARGINAL WITH MORE STABLE AIR AND
COOLER WATERS JUST TO THE NORTH.  HOWEVER...THE GUIDANCE IS NOW
SHOWING CONSIDERABLY MORE INTENSIFICATION...WITH THE
SHIPS/LGEM/HWRF MODELS NEAR HURRICANE STRENGTH IN A COUPLE OF DAYS.
AFTER THAT TIME...AN INCREASE IN SOUTHEASTERLY SHEAR ALONG WITH
DECREASING SSTS SHOULD INDUCE A WEAKENING TREND.  ALTHOUGH THE NEW
NHC FORECAST IS HIGHER THAN THE PREVIOUS ONE...THE FORECAST WILL
STAY LOWER THAN THE BULK OF THE GUIDANCE GIVEN HOW CLOSE FERNANDA
IS TO MORE HOSTILE ENVIRONMENTAL CONDITIONS.


Mmm, el NHC recula ligeramente. Dice que un ambiente estable y aguas frias al N del sistema, deben contrarrestar el ambiente favorable de cizalladura a corto plazo. No obstante, como los modelos dan mas fuerza a la tormenta, ellos lo contemplan, aunque tiran por el lado conservador
