Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sun Aug 13 2023

For the eastern North Pacific...east of 140 degrees west longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Fernanda, located several hundred miles southwest of the
southern tip of the Baja California peninsula.

Western East Pacific (EP99):
Showers and thunderstorms are becoming better organized in
association with an area of low pressure located about 1400 miles
east-southeast of the Hawaiian Islands. Environmental conditions
appear conducive for continued development, and a tropical
depression is likely to form during the next day or so as it moves
westward or west-northwestward at 10 to 15 mph. The system is
forecast to cross into the Central Pacific basin late tonight.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

Off the Coast of Southern Mexico:
A tropical wave continues to produce a large area of disorganized
showers and thunderstorms over the far eastern portion of the east
Pacific. Environmental conditions appear conducive for development
during the next several days, and a tropical depression is expected
to form by midweek while the system moves west-northwestward,
roughly parallel to the coast of southern and southwestern Mexico.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...90 percent.

The last couple of microwave satellite overpasses show a similar scenario, with cold convective curved bands becoming better organized around a low-level center, which appears to be located near the northern edge of the convective cloud mass based on recent visible satellite images. The latest TAFB subjective Dvorak estimate is T-2.0. Based on these data, Invest 98E is upgraded to Tropical Depression Seven-E with an initial intensity of 30 kt. Weak mid-level ridging well to the north of the depression will steer the cyclone toward the west-northwest at about 10 kt over the next few days. Beyond 72 h, the ridge should strengthen enough to cause a turn to the west with a slight increase in forward speed. The NHC forecast track is in best agreement with the HCCA and TVCE consensus models. Environmental conditions are quite favorable for strengthening over the next 48-60 h, with warm ocean temperatures, low vertical wind shear and a relatively moist low to mid-level troposphere. The NHC forecast peaks the system at 75 kt in 48-60 h, which is near the middle of the intensity guidance. The ECMWF version of the SHIPS RI index shows a 52 percent chance of a 65 kt increase in winds over the next 72 h, so there is a chance the cyclone could strengthen more than forecast. After that time, the cyclone is forecast to move into a much drier environment along with slowly decreasing sea-surface temperatures. There is high confidence on significant weakening beyond 72 h due to the very dry airmass that the cyclone will be moving into.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sat Aug 12 2023

For the eastern North Pacific...east of 140 degrees west longitude:

Central East Pacific (EP98):
Showers and thunderstorms continue to become better organized in
association with a low pressure system located several hundred
miles south-southwest of the southern tip of the Baja California
peninsula, and it appears that a tropical depression or tropical
storm could be forming. If these trends continue, advisories would
likely be initiated on this system later today. The low is expected
to move westward to west-northwestward at about 10 mph across the
central portion of the basin during the next few days.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

Western East Pacific (EP99):
A broad area of low pressure associated with a tropical wave is
producing a large area of disorganized showers and thunderstorms
well to the east-southeast of the Hawaiian Islands. Conditions
appear conducive for development of this system, and a tropical
depression is likely to form during the next few days while moving
toward the west or west-northwest at about 10 mph across the far
western portion of the basin, crossing into the Central Pacific
basin late Sunday.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...80 percent.

Off the Coast of Southern Mexico:
An area of low pressure is forecast to form offshore of Central
America and the southern coast of Mexico in a couple of days from
a tropical wave currently moving across the southern portion of
Central America. Environmental conditions are expected to be
conducive for development of this system, and a tropical depression
is likely to form during the early or middle part of next week while
it moves generally west-northwestward, roughly parallel to the coast
of southern and southwestern Mexico.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...high...80 percent.
