HURRICANE JULIO DISCUSSION NUMBER 18
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI EP102014
1100 PM HST THU AUG 07 2014

HURRICANE JULIO HAS ENTERED THE CENTRAL NORTH PACIFIC. SATELLITE
PRESENTATION SHOWS JULIO REMAINS WELL ORGANIZED…WITH PRONOUNCED
BANDING FEATURES REPLACING THE PREVIOUSLY DOMINANT ANNULAR
STRUCTURE. SUBJECTIVE DVORAK INTENSITY ESTIMATES RANGE FROM 4.5…BY
JTWC…TO 6.0…BY CPHC. THE UW-CIMSS ADT IS 5.7…WHILE SAB SPLIT
THE DIFFERENCE AT 5.5…OR 102 KT. THE INITIAL INTENSITY IS SET AT
105 KT FOR THIS FORECAST CYCLE…SLIGHTLY HIGHER THAN THE PREVIOUS
CYCLE BUT STILL REPRESENTING A WEAKENING OVER THE PAST 24 HOURS.

JULIO IS MOVING TOWARD THE WEST NORTHWEST ALONG THE SOUTHERN FLANK
OF A SUBTROPICAL RIDGE EXTENDING ROUGHLY FROM 35N140W THROUGH
38N180W. MODEL TRACK GUIDANCE REMAINS RATHER TIGHTLY PACKED THROUGH
48 HOURS…AND THE FORECAST TRACK HAS CHANGED LITTLE THROUGH THAT
TAU AS IT FOLLOWS TVCN CONSENSUS. HOWEVER…TVCN BEGINS TO DEPART
RATHER SIGNIFICANTLY FROM EARLIER RUNS AT TAU BEYOND 48
HOURS…LIKELY RESPONDING TO A RADICAL RIGHTWARD GFS SWING TO THE
NORTH AT LONG RANGE. AS A RESULT…THE FORECAST TRACK BEGINS TO
PARALLEL ECMWF INSTEAD OF TVCN BEYOND 48 HOURS…ALTHOUGH IT HAS
BEEN ALTERED A BIT NORTH OF THE PREVIOUS FORECAST TRACK TO MAINTAIN
SMOOTHNESS AND CONSISTENCY. IT IS IMPORTANT TO NOTE THAT…WHILE THE
FORECAST TRACK TAKES JULIO PARALLEL TO AND NORTH OF THE MAIN
HAWAIIAN ISLANDS…INTERESTS THERE SHOULD WATCH DEVELOPMENTS WITH
THIS SYSTEM CLOSELY.

THE INTENSITY FORECAST IS UNCHANGED FROM THE PREVIOUS
FORECAST…EXCEPT FOR THE HIGHER INITIAL INTENSITY. SHIPS GUIDANCE
SHOWS GRADUAL WEAKENING THROUGH 120 HOURS…WITH SST BEING THE MOST
SIGNIFICANT WEAKENING FACTOR. WHILE SHEAR IS EXPECTED TO STRENGTHEN
AFTER 24 HOURS AS JULIO APPROACHES AN UPPER TROUGH NORTHWEST OF THE
MAIN HAWAIIAN ISLANDS…THE SHEAR MAGNITUDE IS NEVER MORE THAN 11 TO
13 KT. JULIO IS FORECAST TO REMAIN A MINIMAL HURRICANE AT 72
HOURS…THEN REMAIN A STRONG TROPICAL STORM FROM 72 TO 120 HOURS.

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.
