1. A tropical wave located several hundred miles south-southwest
of the Gulf of Tehuantepec is producing disorganized showers and
thunderstorms.  Environmental conditions are expected to be
conducive for the development of this system over the next several
days, and a tropical depression is likely to form late this weekend
or early next week while the disturbance moves westward to west-
northwestward well away from the coast of Mexico.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.

1. An elongated area of showers and thunderstorms located well to the
southwest of the southern coast of Mexico is associated with a
tropical wave.  Environmental conditions are expected to be
conducive for development of this system, and a tropical depression
is likely to form late this weekend or early next week while the
disturbance moves westward to west-northwestward at about 15 mph.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

WTPN21 PHNC 290200
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 8.0N 102.6W TO 9.6N 110.9W
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 18 TO 23 KNOTS. METSAT
IMAGERY AT 290000Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.9N 102.9W. THE SYSTEM IS MOVING WESTWARD AT 12 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 94E) PREVIOUSLY LOCATED
NEAR 7.9N 101.7W IS NOW LOCATED NEAR 7.9N 102.9W, APPROXIMATELY 1682
NM SOUTH-SOUTHEAST OF SAN DIEGO. ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LLC WITH DEEP CONVECTIVE BANDING
OVER THE NORTHERN SEMI-CIRCLE. UPPER LEVEL ENVIRONMENT IS MODERATELY
FAVORABLE FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-15 KNOTS)
AND GOOD DIVERGENCE ALOFT. GLOBAL MODELS INDICATE STEADY
INTENSIFICATION OVER THE NEXT 24-36 HOURS AS THE SYSTEM TRACKS
WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
300200Z.

Hurricane Barbara Discussion Number   7
NWS National Hurricane Center Miami FL       EP022019
800 PM PDT Mon Jul 01 2019

Passive microwave imagery over the past 6 hours indicates that the
inner-core convection of Barbara has continued to consolidate and a
ragged low- to mid-level eye has formed.  However, a pronounced dry
intrusion has periodically worked its way into the center of the
convective cloud mass, resulting in brief erosions of the eyewall.
Despite the dry air, bursts of deep convection have been developing
near the center and the most recent hi-resolution GOES-17 visible
satellite images suggest that a more robust eyewall is possibly
developing.  Dvorak satellite intensity estimates are T4.5/77 kt
from TAFB and SAB, and UW-CIMSS ADT and SATCON values are T4.5/77
kt and 80 kt, respectively.  Given the occasional appearance of a
ragged cloud-filled eye in visible satellite imagery, the initial
intensity has been increased to 85 kt for this advisory, meaning
that Barbara has rapidly intensified during the past 24 hours.

Barbara's initial motion is 280/13 kt.  There remains no significant
change to the previous track forecast rationale.  Barbara should
turn toward the west-northwest shortly, and that general motion is
forecast to continue for the next 36-48 hours.  After that time, a
passing shortwave trough is expected to weaken the ridge to the
north of the hurricane, allowing Barbara to move more poleward. In
the 96-120 hour period, however, the ridge is forecast to build back
in, forcing Barbara back toward the west.  The new NHC track
forecast is very similar to the previous advisory track, and lies
close to a blend of the TVCN, HCCA, and FSSE consensus models.

The combination of low vertical wind shear, an expanding upper-level
outflow regime, a moist mid-level environment, and SSTs greater than
28 deg C is expected to persist for at least the next 36 hours,
allowing Barbara to continue to rapidly strengthen during that time.
By 48 hours, however, steady weakening is expected to begin due to a
probable eyewall replacement cycle, the beginning of cold upwelling,
and increasing southwesterly wind shear.  On days 4 and 5, more
rapid weakening is forecast due to Barbara moving over sub-26 deg C
water temperatures and into vertical wind shear conditions of more
than 20 kt.  The new official intensity forecast is similar to the
previous advisory, and is a little above the consensus guidance
throughout the entire forecast period, closer to the Decay-SHIPS
model.

Hurricane Barbara Discussion Number   9
NWS National Hurricane Center Miami FL       EP022019
500 AM HST Tue Jul 02 2019

Conventional satellite imagery and microwave data reveal that the
structure of Barbara has improved significantly. The hurricane has
developed an eye surrounded by a ring of very deep convection and
both features have been present during the past several hours.
This improvement in structure has been accompanied by a substantial
intensification, and based on both objective and subjective numbers
of 6.0 on the Dvorak scale, the initial intensity has been adjusted
upward to 115 kt. This is a marked increase of 55 kt since yesterday
at this time. A prevailing warm ocean and low shear could fuel
additional intensification during the next 12 hours or so. However,
the hurricane is forecast to encounter cooler waters and strong
shear primarily beyond 3 days resulting in weakening which could
be much faster by the end of the forecast period.  By the time
Barbara reaches the Central Pacific, it is likely to be a tropical
storm or even a remnant low.

Barbara has been moving steadily toward the west and west-northwest
or 290 degrees ar 12 kt. The hurricane is moving south of a
deep-layer ridge of high pressure extending from the west coast of
the United States westward across the Pacific. Barbara should move
a little more to the northwest around the ridge in about 2 or 3
days, but as soon as the cyclone weakens and becomes shallow, it
will likely move to the west steered by the low-level flow. The NHC
track forecast is similar to the previous one, and it is basically
on top of the multi-model consensus.

NOTE:  Beginning this hurricane season, all National Hurricane
Center eastern Pacific advisory products that utilize local time,
and the corresponding graphical products, will use Hawaiian Standard
Time (HST) instead of Pacific Daylight Time (PDT) or Standard Time
(PST) if the final forecast point is west of 140W.  Since Barbara's
day 5 official forecast point is now west of 140W, advisory products
are now being issued in Hawaiian Standard Time.
