HURRICANE GIL DISCUSSION NUMBER 8

NWS NATIONAL HURRICANE CENTER MIAMI FL EP072013

200 AM PDT THU AUG 01 2013

IT APPEARS THAT GIL IS NO LONGER RAPIDLY INTENSIFYING. THE

CONVECTIVE CANOPY HAS BECOME QUITE COMPACT WITH NO INDICATION OF AN

EYE…AND OUTER BANDING FEATURES HAVE MORE OR LESS DISSIPATED.

DVORAK INTENSITY ESTIMATES HAVE HELD STEADY AT T4.5/77 KT FROM TAFB

AND T4.0/65 KT FROM SAB…SO THE INITIAL INTENSITY IS HELD AT 70

KT.

THE INITIAL MOTION REMAINS 285/10 KT DUE TO THE INFLUENCE OF A

STRONG MID-LEVEL RIDGE EXTENDING FROM THE US/MEXICAN BORDER WESTSOUTHWESTWARD

INTO THE PACIFIC. GIL WILL BE REACHING A BREAK IN THE

RIDGE IN ABOUT 48 HOURS AND SHOULD HAVE A SLOWER FORWARD MOTION

BETWEEN DAYS 3 AND 5. IT SEEMS THAT GIL HAS NOT BEEN ABLE TO FREE

ITSELF FROM THE ITCZ…WHICH SHOULD HELP TO KEEP THE CYCLONE FROM

GAINING MUCH LATITUDE OVER THE NEXT FEW DAYS. THE TRACK GUIDANCE

HAS SHIFTED A BIT MORE TO THE SOUTH MAINLY BEYOND 48 HOURS…AND

THE NHC OFFICIAL FORECAST FOLLOWS THAT TREND.

EVEN THOUGH RAPID INTENSIFICATION APPEARS TO HAVE STOPPED…GIL

STILL HAS THE OPPORTUNITY TO STRENGTHEN SOME MORE. DEEP-LAYER

SHEAR IS EXPECTED TO REMAIN LOW FOR A COUPLE MORE DAYS…AND THE

MORE SOUTHERLY TRACK WILL KEEP THE CYCLONE OVER WARMER SSTS.

DESPITE THIS ENVIRONMENT…ALL OF THE GUIDANCE LIMITS ADDITIONAL

STRENGTHENING WITHIN THE FIRST 24 HOURS OR SO. AFTER THAT

TIME…THE BIGGEST INHIBITING FACTORS APPEAR TO BE INCREASINGLY

STABLE AIR AROUND THE CYCLONE AND A LESS FAVORABLE SHEAR PROFILE.

THE OFFICIAL INTENSITY FORECAST IS AT THE TOP END OR A LITTLE

HIGHER THAN THE GUIDANCE FOR THE FIRST 36 HOURS BUT THEN FOLLOWS A

WEAKENING RATE SIMILAR TO SHIPS…LGEM…AND THE INTENSITY

CONSENSUS.

Technology Test Pilot

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.
