Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Sun Aug 11 2019

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

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Nine-E, located a few hundred miles south of
the southern tip of the Baja California peninsula.

An elongated area of disorganized showers and thunderstorms located
nearly 1000 miles southwest of the southern tip of the Baja
California peninsula is associated with a trough of low pressure.
Environmental conditions are forecast to become more conducive for
development during the next few days, and a tropical depression
could form later this week while the system moves west-
northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.

Public Advisories on Tropical Depression Nine-E are issued under
WMO header WTPZ34 KNHC and under AWIPS header MIATCPEP4.

A late-arriving 1716Z ASCAT-C scatterometer pass indicated the surface wind field was possibly closed at that time, but since then deep convection with tops of -75C to -80C have persisted near and to the west of the mid-level circulation center, suggesting that a low-level center has likely closed off now. Dvorak satellite intensity estimates are T1.5/25 kt from both TAFB and SAB, but the initial intensity is set at 30 kt based on 30-31 kt winds indicated in the aforementioned scatterometer data. The initial motion is estimated to be west-northwestward or 295/12 kt, based primarily on scatterometer and passive microwave fixes. The small cyclone is expected to move west-northwestward around the southern periphery of a deep-layer ridge for the next 3 days until dissipation occurs. The NHC track forecast lies near the southern portion of the guidance envelope, between the TVCE consensus model and the ECMWF-ensemble mean model. The small cyclone only has about 36 hours to strengthen before the system moves over sub-26 deg C SSTs. The shear is forecast to be low at less than 10 kt for the next 72 hours or so, even decreasing to near 5 kt in 24-36 h, which would normally result in significant development. However, intermittent intrusions of dry mid-level air are expected to disrupt the typical intensification process, thus only modest strengthening is forecast through 36 h, after which much cooler waters will induce a weakening trend. The official intensity forecast closely follows a blend of the HCCA and IVCN intensity consensus models.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sun Aug 11 2019

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

Thunderstorm activity has become more concentrated near the center
of a small low pressure system located a few hundred miles south of
the southern tip of the Baja California peninsula. Satellite images
also indicate that the low is gradually becoming better defined. If
this recent development trend continues, then advisories could be
initiated on a tropical depression or a tropical storm later tonight
while the disturbance moves generally west-northwestward, away from
the coast of Mexico. Environmental conditions are expected to become
unfavorable for significant development by early Tuesday.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

An area of disturbed weather located about 1000 miles southwest of
the Baja California peninsula remains disorganized. Environmental
conditions are expected to become gradually more conducive for
tropical cyclone formation by the middle of the week while the
system moves west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.

California peninsula.

Thunderstorm activity associated with a low pressure system located
a few hundred miles south of the southern tip of the Baja California
peninsula have become a little better organized during the past
several hours. In addition, recent satellite-derived surface wind
data indicate that the low has become better defined, with winds
just below tropical-storm strength occurring near and to the east
of the center. If this recent development trend continues, then
advisories could be initiated on a tropical depression or a tropical
storm later this evening while the disturbance moves westward to
west-northwestward, away from the coast of Mexico. Environmental
conditions are expected to become unfavorable for significant
development on Tuesday.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

A disturbance located a little less than 1000 miles southwest of the
