DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 400 PM CDT (2100 UTC), the center of Hurricane Patricia was
located near latitude 18.9 North, longitude 105.2 West. Patricia is
moving toward the north-northeast near 14 mph (22 km/h) and this
motion is expected to continue with some increase in forward speed
tonight and Saturday. On the forecast track, the center of
Patricia should make landfall during the next several hours on the
coast of Mexico between Manzanillo and Cabo Corrientes. After
landfall, the center of Patricia is expected to move quickly
north-northeastward across western and northern Mexico.

Reports from a NOAA Hurricane Hunter aircraft indicate that
Patricia has weakened a little during the past few hours and that
maximum sustained winds are near 190 mph (305 km/h) with higher
gusts. Patricia is a category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Patricia is expected to remain an extremely
dangerous category 5 hurricane through landfall. After landfall,
Patricia is forecast to rapidly weaken over the mountains of Mexico.

Hurricane force winds extend outward up to 35 miles (55 km) from the
center and tropical storm force winds extend outward up to 175 miles
(280 km).

The minimum central pressure from the NOAA Hurricane Hunter Data is
900 mb (26.58 inches).
HAZARDS AFFECTING LAND
———————-
WIND: Hurricane conditions should spread across the hurricane
warning area during the next few hours, with the worst conditions
occurring near where the eye of Patricia makes landfall. Tropical
storm conditions are spreading across portions of the warning area.
Preparations to protect life and property should be rushed to
completion. Hurricane conditions are possible in the hurricane
watch area this afternoon and this evening.

RAINFALL: Patricia is expected to produce total rainfall
accumulations of 8 to 12 inches, with isolated maximum amounts of 20
inches, over the Mexican states of Nayarit, Jalisco, Colima,
Michoacan, and Guerrero through Saturday. These rains could produce
life-threatening flash floods and mud slides.

STORM SURGE: An extremely dangerous storm surge is expected to
produce significant coastal flooding near and to the right of where
the center makes landfall. Near the coast, the surge will be
accompanied by large and destructive waves.

SURF: Swells generated by Patricia are already affecting portions
of the southern coast of Mexico, and will spread northwestward
during the next day or so. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

HURRICANE PATRICIA DISCUSSION NUMBER 16
NWS NATIONAL HURRICANE CENTER MIAMI FL EP202015
400 PM CDT FRI OCT 23 2015

A NOAA Hurricane Hunter aircraft reported that Patricia changed
little in intensity through about 1800 UTC. The aircraft measured
192 kt flight-level winds at 700 mb in the southeastern eyewall,
with a 166 kt surface wind estimate from the Stepped Frequency
Microwave radiometer. The central pressure estimated from an eye
dropsonde was 879 mb. Since that time, the eye has become
cloud-filled, and data from the plane suggest the formation of an
outer wind maximum, with decreasing winds in the eyewall, and an
increasing central pressure. All of these indicate that the
hurricane is weakening. The initial intensity is reduced to 165 kt,
and this could be generous. Patricia is expected to remain a
Category 5 hurricane until landfall in southwestern Mexico in a few
hours. After landfall, a combination of the mountainous terrain of
Mexico and increasing shear should cause the cyclone to rapidly
weaken, with the system likely to dissipate completely after 36
hours, if not sooner.

Patricia is now moving north-northeastward with an initial motion
of 015/12. The cyclone is recurving into the westerlies between a
mid-level anticyclone to its east and a deep-layer trough over
northwestern Mexico and the southwestern U. S., and a faster motion
toward the north-northeast is expected for the rest of the cyclone’s
life. The new forecast track is shifted a little to the east of the
previous track based on the initial position and motion. It lies
near the center of the guidance envelope at 12 hours and little to
the left of the center after that time.

The global models continue to depict the development of a cyclone
near the Texas coast over the weekend. This system should be
non-tropical in nature. However, this cyclone is expected to draw
significant amounts of moisture from Patricia’s remnants, and could
result in locally heavy rainfall over portions of the northwestern
Gulf of Mexico coastal area within the next few days. Refer to
statements from local National Weather Service forecast offices for
details.
KEY MESSAGES:

1. Confidence is high that Patricia will make landfall in the
hurricane warning area along the coast of Mexico as an extremely
dangerous category 5 hurricane during the next few hours.
Preparations to protect life and property in the hurricane warning
area should have been completed, or rushed to completion, as
tropical storm conditions are spreading across the area and
hurricane conditions are about to occur. Residents in low-lying
areas near the coast in the hurricane warning area should evacuate
immediately, since the storm surge could be catastrophic near and to
the east of where the center makes landfall.

2. In addition to the coastal impacts, very heavy rainfall is
likely to cause life-threatening flash floods and mud slides in the
Mexican states of Jalisco, Colima, Michoacan and Guerrero continuing
into Saturday.

3. The NOAA Hurricane Hunter aircraft reports that at this time, the
Category 5 winds are occurring over a very small area near the
center – about 15 miles across.

In 1995 At Maui High Performance Computing Center The Maui Scientific Analysis & Visualization of the Environment Program was first incubated. I was the principal investigator of this independant research project which was a joint development between MHPCC, Silicon Graphics Computers (SGI) & NKO.ORG. Using SGI Cosmo Worlds software, we pioneered the development of Internet based 3D virtual reality GIS based interactive worlds. In 1996 with a network of seven high performance SGI workstations we pioneered development of live streaming MPEG-1, MPEG-2, MPEG-4, Real Video and QuickTime Streaming Server utilizing Kassenna MediaBase software. In Maui 2002 we pioneered and tested the first wireless live streaming video using laptop computers and Maui Sky Fiber's portable 3G wireless device. In Maui we pioneered live streaming video using usb modems from AT&T , Verizon as well as live streaming from iPhone 3 over 3G wireless networks. Today The Maui S.A.V.E. Program has diversified into storm tracking including visualization and analysis of large, memory-intensive gridded data sets such as the National Hurricane Center's wind speed probabilities. I volunteer my services to numerous Disaster Services Organizations. In June 2013 I returned from Hurricane Sandy deployment as a computer operations service associate with the Disaster Services Technology Group assisting as The American Red Cross migrated from a Disaster Response Operation to Long Term Recovery Operations. Pioneering the production/editing and Internet distribution of HD video to sites like Youtube.com and Vimeo.com we are shining the light towards environmental and peace efforts of humans across the globe. Since 1992 I have held the vision of establishing Maui, Hawaii as the environmental sciences center of the world. After His Holiness the 14th Dalai Lama of Tibet came to Maui This vision has expanded to establishing Maui as the environmental & peace center of the world.
