SUMMARY OF 300 PM MDT…2100 UTC…INFORMATION
———————————————-
LOCATION…10.8N 114.0W
ABOUT 880 MI…1415 KM SSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA
MAXIMUM SUSTAINED WINDS…35 MPH…55 KM/H
PRESENT MOVEMENT…WNW OR 290 DEGREES AT 12 MPH…19 KM/H

WATCHES AND WARNINGS
——————–
There are no coastal watches or warnings in effect.
DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 300 PM MDT (2100 UTC), the center of Tropical Depression Eight-E
was located near latitude 10.8 North, longitude 114.0 West. The
depression is moving toward the west-northwest near 12 mph (19 km/h)
and this general motion is expected to continue for the next couple
of days.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Some strengthening is forecast during the next 48 hours, and the
depression is expected to become a tropical storm by tonight or
early Friday.

The estimated minimum central pressure is 1006 mb (29.71 inches).

TROPICAL DEPRESSION EIGHT-E DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL EP082016
300 PM MDT THU JUL 21 2016

An ASCAT-B pass at 1742Z showed that the area of low pressure
located well southwest of Mexico now has a well-defined center, and
the geostationary imagery shows a curved convective band wrapping
nearly halfway around the system. Given this, the low is now
classified as a tropical cyclone. The initial intensity is set to
30 kt based on the ASCAT data, which is also in agreement with the
latest Dvorak estimate from SAB. The depression will be moving over
SSTs of 28C or higher for the next couple of days, but will also be
in a moderate easterly to northeasterly shear environment during
that time. Given these conditions, gradual intensification is
forecast in the short term. The cyclone is forecast to peak in
about 72 hours before it moves over cooler waters and into a more
stable environment, which should result in slow weakening. The NHC
intensity prediction is close to the intensity consensus through the
forecast period.

The initial motion estimate is a somewhat uncertain 290/10 given the
recent formation of the system. The dominant steering mechanism for
the first 2-3 days of the forecast period will be a large
subtropical ridge that will migrate westward from central North
America over the eastern Pacific. This should keep the cyclone
moving generally west-northwestward for the first 48 hours or so.
After that time, there is an increase in the spread of the guidance.
The ECMWF and HWRF show the cyclone turning more poleward into a
weakness in the ridge caused by an upper-level low, with the ECMWF
showing some northward motion possibly due to the influence of
Tropical Storm Fred to the the northeast. The GFS, GEFS mean, and
COAMPS-TC show a more westward track with the cyclone staying south
of the ridge. For now the NHC track forecast is down the middle of
the guidance envelope and is very close to the multi-model
consensus. Given the large spread in the guidance, the track
forecast uncertainty is higher than usual late in the forecast
period.

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.
