Tropical Depression Blas Track and Winds Seen By the Racers

Complements of Weather Routing Incorporated: Winds in the Vicinity of the Racers remain light to moderate with an increasing gradient to the south. AT 08/15Z, NEWLY UPGRADED TROPICAL STORM CELIA WAS CENTERED NEAR 12.6N 112.8W (600NM SSW OF CABO SAN LUCAS), MOVING W’WARD AT 08KTS, WITH MAXWINDS 40- 50KTS. GALE RADIUS IS 030NM N’RN SEMICIRCLE, 000NM S’RN SEMICIRCLE. Tropical Depression 4E has become much better organized and is now TROPICAL STORM Celia. This system will slowly strengthen into a HURRICANE through the 10th as moves W-WNW. The system should peak in intensity by the 12th, before weakening over cooler waters on the 13th as moves WNW’ward.

Weather Routing Incorporated indicates Blas will not have a large impact on the fleet

Weather Routing Inc. is Proud to be the Official Weather Provider for the Singlehanded TransPac Race Prepared: July 07 15:40z FM: Weather Routing Inc. (WRI) Synopsis: Good morning. Please see the section on HURRICANE Blas and TROPICAL DEPRESSION 4E. An area of HIGH PRESSURE is now located near 40N/160W, and has ridging E’ward to 130W. This HIGH will meander to 44N/155W through the 10th, with ridging SE’ward to 30N/130W at that time. The remnants of Agatha are now centered near 23N/140W and consists of a weak LOW level circulation. This will transition into a weak trough of LOW pressure, and will move W’ward, extending from 21N/147W N’ward to 26N on the 10th. An upper level LOW is now located near 29N/141W, and this will weaken into an upper level trough while moving W’ward, extending from 27N/146W SW’ward to 24N on the 10th. Severe Weather Potential/Advisories: There are no advisories at this time. Please monitor NOAA All Hazards Radio on your VHF for the latest official warnings and advisories from The National Weather Service. Hedge Forecast: We are very confident in the forecast for all grids, as the track of HURRICANE Blas is expected to remain just south of the grids. The west turn of Blas has HIGH confidence as once the system rapidly weakens, it will be steered more by the ridge and to the west. Regardless of the track though, there will be enhanced conditions in grids JJ and KK below. Conclusions: The remnants of Agatha are not a major concern. For Blas, the system will be weakening rapidly in the next 3 days, and by the 10th, will be a post-tropical GALE. The weakening is expected as the system moves over cooler waters. The system will be located just south of grids KK and JJ on the 09th-10th, so it would be best for vessels to remain close to the n’rn half of those grids into the long range for maximum safe berth from the system. The cluster of vessels farther west should remain safely ahead of HURRICANE Blas, with the cluster of vessels farther east remaining safely north and east of the system. In the long range, we will need to also watch closely the track of TROPICAL DEPRESSION 4E, and any impacts to the grids in the 6-8 day timeframe. For Grid II, expect main N-NE’ly gentle to moderate breezes through the 10th, with building but long period SE-S’ly swells due to TROPICAL activity to the south. For Grid CC and DD, similar conditions are expected. Farther south, expect more enhanced NE’ly winds in JJ due to Blas through the 10th, along with building swells, up to 11ft by the 10th. Some scattered showers/squalls are expected in the s’rn portion of the grid on the 09th-10th due to Blas. For KK, similar conditions are expected.
