Post-Tropical Cyclone Genevieve Discussion Number  22
NWS National Hurricane Center Miami FL       EP122020
200 PM PDT Fri Aug 21 2020

Cool waters and less favorable thermodynamic conditions have
continued to take a toll on Genevieve.  The system has not had any
deep convection for more than 12 hours, and it is unlikely that any
organized deep convection will return.  As a result, Genevieve has
become a post-tropical cyclone and this will be the final NHC
advisory on this system.  The initial wind speed is set at 35 kt,
which is in agreement with recent scatterometer data.  The
post-tropical cyclone should continue to gradually weaken over
cooler water during the next couple of days, and the global model
guidance indicates that the circulation will become an open trough
within 72 hours.

The cyclone continues to move northwestward at about 10 kt.  A
northwestward motion is forecast to continue over the next couple of
days, but the forward speed of the system is expected to slow as it
becomes increasing shallow and is steered by the weaker low-level
flow.  The track guidance remains tightly clustered and the new
foreast is an extension of the previous advisory.

This is the final NHC advisory on Genevieve.  Additional information
on the post-tropical cyclone can be found in High Seas Forecasts
issued by the National Weather Service, under AWIPS header
NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at
ocean.weather.gov/shtml/NFDHSFEPI.php

Tropical Storm Genevieve Discussion Number  21
NWS National Hurricane Center Miami FL       EP122020
900 AM MDT Fri Aug 21 2020

Genevieve continues to gradually weaken while it encounters cooler
waters and light to moderate southerly shear. Deep convection
associated with the system dissipated around the time of the
previous advisory, and the cyclone is now comprised of a swirl of
low- to mid-level clouds.  The initial intensity has been reduced to
40 kt, which is a blend of the latest TAFB Dvorak T- and CI-numbers.
Genevieve is expected to continue to gradually weaken today as it
moves over SSTs of 24-25 degrees Celsius.  It is unlikely that
organized deep convection will return, and Genevieve is expected to
become a post-tropical cyclone later today. The cyclone's winds are
forecast to drop below tropical storm strength within 12 hours, and
the remnant low should continue to spin down over cooler waters west
of the Baja California peninsula during the next couple of days.
The global models indicate that the remnant low will dissipate in
about 72 hours.

Genevieve is moving northwestward at about 9 kt.  The cyclone should
continue on this general heading over the next couple of days as it
moves around the southwestern side of a mid-level ridge over
northern Mexico. The remnant low is forecast to decelerate by Sunday
as it becomes vertically shallow and is steered by the weaker
low-level flow.

Large swells from Genevieve that are spreading northward along
portions of the west coast of the Baja California peninsula will
gradually subside on Saturday.

在睡夢中減弱為熱帶風暴原文：

Tropical Storm Genevieve Discussion Number  18
NWS National Hurricane Center Miami FL       EP122020
300 PM MDT Thu Aug 20 2020

Dry and stable air continues to be drawn into Genevieve's
circulation.  This is noted by a slow erosion of convection over
the southwestern semicircle, and warming cloud tops over
the past several hours, indicating weakening. An Air Force Reserve
Hurricane Hunter aircraft investigating the system this afternoon
measured peak 700 mb flight-level winds of 71 kt, which  reduce to
64 kt at the surface, with peak SFMR winds of 57 kt. A blend of
these values supports lowering the initial intensity to 60 kt.

Genevieve should continue to gradually weaken as it moves over
progressively lower oceanic temperatures. By Friday, the cyclone is
expected to cross the 26 C SST isotherm, and it will reach waters
cooler than 24 C by early Saturday. These much cooler waters should
cause the cyclone to degenerate to a remnant low by late Saturday.
The latest NHC intensity forecast is little changed from the
previous one, and is near the HFIP corrected consensus HCCA.

Genevieve continues to move northwestward at 10 kt, paralleling the
coast of the southern Baja California Peninsula. This general motion
is expected to continue until the cyclone dissipates later in the
forecast period. On this track, Genevieve will begin to move away
from the peninsula tonight. The NHC forecast track is very little
changed from the previous one and is in the middle of the tightly
clustered track guidance.

Key Messages:

1. The center of Genevieve is forecast to pass just west of the Baja
California peninsula through this evening,  with tropical storm
conditions expected to continue over portions of this area during
this time.

2. Rainfall from Genevieve will continue to decrease in intensity
over southern Baja California Sur, although some instances of flash
flooding and mudslides remain possible through this evening.

3. Large swells generated by Genevieve will affect portions of
the west-central coast of Mexico and the coast of the southern Baja
California peninsula through Friday.

繼續將乾燥穩定的空氣吸入Genevieve的
循環中。
在西南半圓上對流緩慢侵蝕，並
在過去幾個小時內云層變暖，表明減弱了這一點。空軍預備役
颶風獵人飛機今天下午對系統進行了
測量，測得700 mb的飛行高度風峰值為71 kt，
表面降到64 kt，SFMR的峰值風為57 kt。
這些值的混合有助於將初始強度降低到60 kt。

隨著
海洋溫度逐漸降低，Genevieve應當繼續逐漸減弱。
預計到週五，旋風將超過26 C SST等溫線，到
星期六週六，其水溫將低於24C。這些涼爽得多的水應
導致旋風在周六晚些時候退化為殘餘低點。
最新的NHC強度預測與
之前的預測幾乎沒有變化，並且接近HFIP校正的共識HCCA。

吉納維芙繼續以10 kt的速度向西北移動，與
南下加利福尼亞半島的海岸平行。
預計該總體運動將持續到旋風分離器在稍後消散。
預測期。在這個軌道上，吉納維芙
今晚將開始遠離半島。NHC的預測軌跡
與前一個軌跡幾乎沒有變化，並且處於緊密
聚集的軌跡指導的中間。

重要信息：

1.預報吉納維芙中心將在
今晚穿過加利福尼亞下加利福尼亞半島以西，
預計熱帶風暴條件將在
這段時間內繼續在該地區的部分地區蔓延。

2.
儘管
今晚仍有可能發生山洪氾濫和泥石流，但來自Genevieve的降雨將繼續降低南下加利福尼亞州南部的強度。

3.吉恩維芙（Genevieve）產生的大浪將影響到

WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

The Hurricane Warning for the Southern Baja California peninsula
from Los Barriles to Todos Santos has been replaced with a Tropical
Storm Warning.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Baja California peninsula from Los Barriles to Cabo San Lazaro

A Tropical Storm Watch is in effect for...
* The east coast of the Baja California peninsula from Los Barriles
to La Paz

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 hours. Tropical storm conditions have already been occurring
along the southern tip of the Baja California peninsula since last
night, and these conditions continue to spread northward over the
Southern Baja California peninsula, especially over higher terrain.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the center of Hurricane Genevieve was
located near latitude 23.3 North, longitude 111.4 West. Genevieve is
moving toward the northwest near 12 mph (19 km/h) and this motion is
expected to continue through Saturday. On the forecast track, the
center of Genevieve is expected to pass just to the southwest and
west of the southern portion of the Baja California peninsula today,
and move away from the peninsula on Friday.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Further gradual weakening is expected today and through the
weekend.  However, Genevieve is expected to remain a hurricane
through much of today while it passes just to the southwest and
west of the southern Baja California peninsula.

Hurricane-force winds extend outward up to 30 miles (45 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km). An automated observing site near the Cabo San Lucas
Marina recently reported a wind gust to 46 mph (74 km/h).

The estimated minimum central pressure is 984 mb (29.06 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions will spread northward within the
warning area in the southern Baja California peninsula through today
and may linger into tonight.  Tropical storm conditions are possible
within the watch area through the early afternoon, especially over
higher terrain.

RAINFALL:  Genevieve is expected to produce additional rainfall
amounts of 2 to 4 inches across southern Baja California Sur, with
isolated storm totals of 12 inches across far southern Baja
California Sur. This rainfall may lead to life-threatening flash
flooding and mudslides.

SURF:  Large swells produced by Genevieve are affecting portions of
the west-central coast of Mexico and are spreading northward along
the coast of the Baja California peninsula.  These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Hurricane Genevieve Discussion Number  14
NWS National Hurricane Center Miami FL       EP122020
300 PM MDT Wed Aug 19 2020

Genevieve's satellite presentation has continued to degrade this
afternoon with the eye becoming less distinct in visible imagery and
a warming of the cloud tops in the surrounding ring of convection.  
Objective and subjective Dvorak T-numbers have continued to fall,
and the reduction in wind speed has been confirmed by recent data
from an Air Force Reserve reconnaissance aircraft that has provided
a couple of center fixes during its mission this afternoon.  
Somewhat surprisingly, the plane only reported peak flight-level
winds of 82 kt and SFMR winds of 69 kt. The latest minimum pressure
reported by the aircraft was 974 mb.  Since the aircraft only flew a
single alpha pattern, it is possible that the strongest winds were
not captured.  Therefore the initial intensity has been
conservatively adjusted to 80 kt.

DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the center of Hurricane Genevieve was
located near latitude 20.9 North, longitude 109.7 West. Genevieve is
moving toward the north-northwest near 9 mph (15 km/h).  A turn
toward the northwest is expected this afternoon or tonight, with
this motion continuing through Friday night.  On the forecast
track, the center of Genevieve is expected to move near but just
southwest of the southern portion of the Baja California peninsula
tonight and Thursday, and move away from the peninsula on Friday.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts.  Genevieve is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Gradual weakening is forecast over the next
couple of days, but Genevieve is expected to remain a strong
hurricane while it passes west of the southern Baja California
peninsula.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).

The estimated minimum central pressure is 959 mb (28.32 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected within the hurricane
warning area tonight and Thursday.  Tropical storm conditions are
expected within the warning area in the southern Baja California
peninsula by this afternoon, especially over higher terrain.  
Tropical storm conditions are possible within the watch area by
tonight or Thursday morning, especially over higher terrain.

RAINFALL:  Genevieve is expected to produce rainfall amounts of 3 to
6 inches with isolated totals of 10 inches across portions of far
southern Baja California Sur. This rainfall may lead to
life-threatening flash flooding and mudslides.

SURF:  Large swells produced by Genevieve are affecting portions of
the southern coast of Mexico and will spread northward along the
southwestern and west-central coast of Mexico to the Baja California
peninsula through Thursday.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
