NWS National Hurricane Center Miami FL EP162022
600 PM MDT Sat Oct 01 2022
The satellite presentation of Orlene has quickly improved during the
past several hours. A warm and well-defined eye has emerged in
GOES-17 satellite imagery, surrounded by a solid ring of deep
convection with infrared cloud tops colder than -70 degrees Celsius.
The initial intensity is set at 90 kt for this advisory based on
recent satellite intensity estimates.
Based on the higher initial intensity, the near-term intensity
forecast has been raised to show additional strengthening in the
next 12-24 h while environmental conditions remain conducive for
intensification. No changes were made to the track forecast with
this special advisory.
Key Messages:
1. Hurricane conditions are expected in the Islas Marias Sunday
night, with tropical storm conditions beginning late Sunday.
Hurricane conditions are possible over portions of west-central
mainland Mexico starting on Monday. Tropical storm conditions are
expected within the tropical storm warning area along the
west-central coast of Mexico on Sunday. Tropical storm conditions
are possible over other portions of southwestern and west-central
Mexico in the tropical storm watch area tonight or Sunday.
