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

1. Showers and thunderstorms continue to become less organized in
association with a broad area of low pressure located about 700
miles south of the southern tip of the Baja California peninsula.   
Environmental conditions are expected to become increasingly
unfavorable, and development of this system is now unlikely.  The
disturbance is forecast to move slowly west-southwestward during the
next couple of days.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.

2. A broad trough of low pressure is expected to form a couple of
hundred miles south of the coasts of southern Mexico, El Salvador,
and Guatemala in a day or two.  Environmental conditions appear
favorable for some development thereafter, and a tropical depression
could form by the end of the week as the system moves slowly
northwestward or northward.  Regardless of development, this system
could produce heavy rainfall over portions of Central America and
southern Mexico later this week and into the weekend.  See products
from your local meteorological service for more information.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

1. A broad area of low pressure located about 700 miles south of the
southern tip of the Baja California peninsula is producing limited
shower and thunderstorm activity well west of its center.  
Significant development of this system is not expected due to strong
upper-level winds and dry air in the surrounding environment.  The
disturbance is forecast to move slowly west-southwestward during the
next couple of days.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

2. A broad area of low pressure along the eastern Pacific monsoon

Baja California peninsula is producing a large area of disorganized
showers and thunderstorms.  Some gradual development is possible
over the next few days as the system moves slowly westward.

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

1. Showers and thunderstorms have changed little in organization today
in association with a broad area of low pressure located about a
hundred miles south of Puerto Angel, Mexico. Environmental
conditions appear somewhat conducive for additional development, and
a tropical depression could still form by this weekend, as long as
the system remains over water while drifting north-northeastward.
Heavy rainfall will be possible over portions of Central America and
southern Mexico through early next week. See products from your
local meteorological service for more information.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

2. Showers and thunderstorms have changed little in organization this
afternoon in association with a broad area of low pressure located
about 1100 miles southwest of the southern tip of the Baja
California peninsula.  Environmental conditions appear marginally
conducive for some additional development over the next few days,
and a tropical depression could form by early next week while the
system moves slowly westward.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

1. Recent satellite and microwave imagery indicate that the area of low
pressure located about 1100 miles southwest of the southern tip of
the Baja California peninsula has become better-defined while
associated shower and thunderstorm activity is showing signs of
organization. Therefore, this system will likely become a tropical
depression later today or tonight as it moves slowly westward. Early
next week, conditions are expected to become unfavorable for further
development.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

Tropical Depression Three-E Discussion Number   1
NWS National Hurricane Center Miami FL       EP032021
200 PM PDT Sat Jun 12 2021

The disturbance that has been tracked westward for the past several
days across the open waters of the the tropical eastern Pacific has
finally established a sufficiently well-defined low-level
circulation to be designated as Tropical Depression Three-E.
Convection increased last night and began to consolidate, while
satellite images and microwave data this morning indicated that
there was evidence of a well-defined low developing. This was later
confirmed by a pair of ASCAT overpasses. These overpasses showed a
compact radius of maximum winds. And, although the ASCAT-A data
had a few vectors between 30-35 kt, these were not homogeneous and
appeared unrepresentative of the system's intensity. In addition,
the rather ragged satellite appearance and the Dvorak intensity
estimate of 2.0 from SAB are suggestive that this system should be
initialized as a 30-kt depression for this advisory.

The environment surrounding the depression is moderately conducive
for gradual strengthening, with SSTs of 27-28 degrees C, mid-level
RH values between 50-60 percent, and vertical wind shear of about
5-10 kt. These conditions are expected to continue for the next 2-3
days. By 72 h, dry air and subsidence are expected to hinder any
further intensification and should begin a weakening trend. By late
in the forecast period, the system is forecast to cross the 26
degree C isotherm, which should hasten the pace of weakening. The
official intensity closely follows the HFIP corrected consensus
HCCA, which shows the depression becoming a tropical storm tonight,
and levels off its intensity by 48 h, followed by a weakening trend
after 60 h.

A mid-level ridge to the north of the cyclone is steering it at a
somewhat uncertain 275/08 kt. This ridge is forecast by nearly all
of the models to weaken over the next couple of days, leaving the
depression in a region of very weak steering currents through
early next week. A mid-upper level trough digging southward to the
northwest of the cyclone should induce a northerly component of
motion along with an increase in forward speed by midweek. As
said, there is good agreement on the pattern, however, the models
vary greatly on how abruptly they slow the system. This is resulting
in a track model spread of about 300 n mi by 72 h. The NHC track
forecast tries to split the difference by closely following the TVCE
and TVCN consensus aids.
