Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Tue Sep 17 2019

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

The National Hurricane Center is issuing advisories on Hurricane
Kiko, located over the southwestern part of the basin.

Showers and thunderstorms have increased in association with a
well-defined area of low pressure located about 600 miles south-
southwest of Manzanillo, Mexico, and is close to becoming a
tropical depression. Advisories on this system could be initiated
later this morning or this afternoon while the low moves
west-northwestward or northwestward.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 5 days...high...near 100 percent.

Satellite images indicate that the low pressure area located about
250 miles south of Acapulco is becoming better defined and is close
to becoming a tropical storm. Advisories will likely be initiated
later this morning, and this system will continue to move west-
northwestward near or just offshore of the coast of Mexico during
the next few days. Interests along the southwestern coast of Mexico
should monitor the progress of this system, and watches or warnings
could be required later today.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 5 days...high...near 100 percent.

Disorganized cloudiness and showers near and just west of Central
America are associated with a tropical wave. Gradual development of
this system is possible during the next several days while the wave
moves westward or west-northwestward at 5 to 10 mph. Locally heavy
rainfall is possible along the coasts of El Salvador, Guatemala
and southeastern Mexico during the next few days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...40 percent.

Issued at 200 AM PDT Tue Sep 17 2019 000 WTPZ43 KNHC 170852 TCDEP3 Hurricane Kiko Discussion Number 20 NWS National Hurricane Center Miami FL EP132019 200 AM PDT Tue Sep 17 2019 The northeasterly shear impacting Kiko has still not let up. Satellite imagery shows an irregular shaped central dense overcast with the anvils being forced downshear. A blend of the latest subjective and objective intensity estimates suggest the initial intensity has decreased to 70 kt, and this value may be a little generous based on a recent scatterometer pass. Kiko is moving slowly westward. All of the track guidance indicate that a turn to the west-southwest should be commencing very soon as the cyclone becomes steered by a mid-level ridge to its northwest. This steering pattern should remain in place for the next couple of days, before the ridge weakens and Kiko becomes steered to the west to west-northwest by a ridge to its northeast. Late in the forecast period, a new ridge should develop to the northwest of Kiko, causing another turn to the west-southwest. All the while, the steering currents will be fairly weak, resulting in a slow forward motion for the next several days. The official NHC forecast was adjusted only slightly to the south through 72 hours due to a shift in the consensus aids. The shear is expected to weaken Kiko to a tropical storm later today. By tonight, this shear is expected to diminish, which could allow for some re-strengthening. However, moderately stable air surrounding the system, subsidence from the ridge to the northwest, and marginal sea surface temperatures should keep the strengthening at a minimum before the shear returns in a couple of days. This re-strengthening is forecast by most of the guidance, and although the NHC forecast makes Kiko a hurricane again, the forecast intensity is a little lower than some of the most reliable consensus aids during that time period. Once the shear returns, Kiko is expected to begin weakening once again and should become a tropical storm by 72 hours.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Mon Sep 16 2019

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

The National Hurricane Center is issuing advisories on Hurricane
Kiko, located over the southwestern part of the basin.

Showers and thunderstorms remain limited in association with a
well-defined area of low pressure located about 650 miles
south-southwest of Manzanillo, Mexico. Any significant increase in
the thunderstorm activity would lead to the formation of a tropical
depression later today or tonight, while the disturbance moves
west-northwestward or northwestward.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

Recent satellite-derived wind data indicate that the large area of
low pressure located a few hundred miles south-southeast of
Acapulco, Mexico, is becoming better organized. If this development
trend continues, then a tropical depression or tropical storm could
form later today or tonight. This system will continue to move
west-northwest near or just offshore of the coast of Mexico for the
next few days. Interests along the southwestern coast of Mexico
should monitor the progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

Disorganized cloudiness and showers near and just west of Central
America are associated with a tropical wave. Gradual development of
this system is possible during the next several days while the wave
moves westward or west-northwestward at 5 to 10 mph. Locally heavy
rainfall is possible along the coasts of El Salvador, Guatemala
and southeastern Mexico during the next few days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.

Satellite images show a less organized central dense overcast feature with no evidence of an eye. There is a sharp edge in the convective pattern on the north side of the system, suggestive of continued northerly wind shear. The initial wind speed is lowered to 75 kt, which is near the high end of the latest satellite intensity estimates. Kiko remains a very compact system with its tropical-storm-force winds and rain bands extending only about 50 n mi from the center. Additional weakening seems likely during the next 24 hours due to the continued effects of northerly shear, dry air, and marginally warm SSTs, and the NHC forecast shows Kiko falling below hurricane intensity during that time. The models show Kiko re-strengthening a little or maintaining its intensity on Wednesday and Thursday as it moves over slightly warmer waters and into a region of lower shear. However, weakening should resume by the end of the week when the cyclone moves into a less favorable atmospheric environment. The NHC intensity forecast follows the trend of the guidance and is in best agreement with the intensity consensus aids. Kiko continues to only crawl westward in relatively weak steering currents. A ridge building to the northwest of Kiko over the central Pacific is forecast to steer the cyclone west-southwestward on Tuesday and Wednesday. After that time, the ridge is expected to weaken allowing Kiko to turn westward or west-northwestward later this week, followed by another turn to the southwest by the end of the forecast period. Regardless of the details of the track forecast, the bottom line is that Kiko is expected to continue its slow trek for several more days.
