Issued at 800 PM PDT MON JUL 27 2015 000 WTPZ33 KNHC 280232 TCPEP3 BULLETIN TROPICAL DEPRESSION EIGHT-E ADVISORY NUMBER 2 NWS NATIONAL HURRICANE CENTER MIAMI FL EP082015 800 PM PDT MON JUL 27 2015 ...TROPICAL DEPRESSION NOT WELL ORGANIZED... SUMMARY OF 800 PM PDT...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...16.0N 127.0W ABOUT 1210 MI...1945 KM WSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 PM PDT (0300 UTC), the center of Tropical Depression Eight-E was located near latitude 16.0 North, longitude 127.0 West. The depression is moving toward the west-northwest near 14 mph (22 km/h). This general motion is expected to continue with a turn toward the west by late Wednesday. Maximum sustained winds remain near 35 mph (55 km/h) with higher gusts. Slow strengthening is possible through Tuesday, and the depression could become a tropical storm within the next day or so. Weakening is expected to begin on Wednesday. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 200 AM PDT. $$ Forecaster Kimberlain

Tropical Depression EIGHT-E Forecast Discussion Number 1
2015-07-27 22:55:24| National Hurricane Center (East Pacific)
Issued at 200 PM PDT MON JUL 27 2015 000 WTPZ43 KNHC 272055 TCDEP3 TROPICAL DEPRESSION EIGHT-E DISCUSSION NUMBER 1 NWS NATIONAL HURRICANE CENTER MIAMI FL EP082015 200 PM PDT MON JUL 27 2015 The low pressure system located more than 1000 n mi west-southwest of the Baja California peninsula has finally acquired enough persistent deep convection near the center for it to be upgraded to a tropical depression. An 1831 UTC ASCAT-B overpass indicated a well-defined circulation center and inner-core wind field containing several 30-31 kt surface wind vectors at a distance of 35-40 nmi to the northeast and southeast of the center. Although the depression is a sheared tropical cyclone, a T2.0/30 kt Dvorak satellite classification from TAFB also justifies upgrading the low to a tropical depression at this time. The initial motion estimate is 290/14 kt, which is based primarily on microwave and ASCAT satellite fixes. The NHC model guidance is in good agreement on the tropical cyclone moving toward the west-northwest at 12-14 kt for the next 72 hours or so due to a strong deep-layer ridge locate to its north. After that, however, the guidance diverges significantly with the ECMWF model taking a very weak cyclone or trough west-southwestward, the GFS and HWRF models moving the system westward, while the GFS-ensemble mean and the remainder of the models keep the depression on a slower west-northwestward track. The NHC official forecast track basically lies down the middle of the guidance suite throughout the forecast period and is close to the consensus model TVCE. The cyclone is not expected to intensify much due to persistent moderate northwesterly vertical wind shear and the cyclone moving over marginal sea-surface temperatures after 72 hours. There will also likely be occasional intrusions of drier and more stable air, which lies just to the north of the forecast track, into the cyclone. However, the well-established southerly low-level inflow of unstable air should help to maintain enough convection to keep this system as a tropical cyclone throughout the forecast period. The NHC intensity forecast is similar to the ICON consensus model.

SUMMARY OF 200 PM PDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...15.6N 126.1W ABOUT 1170 MI...1880 KM WSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WNW OR 285 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ Satellite imagery and satellite-derived wind data indicate that a tropical depression has formed well to the west-southwest of the southern tip of the Baja California peninsula. At 200 PM PDT (2100 UTC), the center of Tropical Depression Eight-E was located near latitude 15.6 North, longitude 126.1 West. The depression is moving toward the west-northwest near 16 mph (26 km/h) and this general motion is expected to continue for the next 48 hours. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Slow strengthening is possible during the next 48 hours, and the depression could become a tropical storm by Tuesday. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- None.
