Tropical Storm Greg Eastern Pacific 2005

Information on Tropical Depression Greg 2005

08AM MDT 16/08/05 Despite computer models indicating that TD Greg should strengthen, wind shear disrupted the cyclonic action and Greg spun apart into a tropical low. The remains of the storm continued to move westward into the Pacific and reformation is not anticipated. Greg is now well west of the Baja California Threat Zone. No further updates will be issued on this storm until historical data is available.

On 14/08 the storm appeared to come to a stop as northerly wind shear began effecting the cyclonic action of the storm. It was reduced at mid day to a tropical depression.

Tropical storm Greg gain only slightly in intensity and slowed, to as little as 3kts earlier 13/08. At one point the storm was moving NNW, bringing it only 5 miles closer to Baja California during the day. Strong wind shear continued from 12/08 and may have been responsible for the degradation of the storm. However, computer models are still showing Greg with the potential to become a hurricane by Wednesday. By that time the storm should be well west of being any threat to Baja California. It should be considered as well, that a hurricane with such low forward speed can become very unpredictable, and change direction radically. None of the computer models are showing Greg as a threat to the Baja peninsula at this time.

It was first thought that Greg would be forced further north, on the trailing side of Hurricane Fernanda. Rotational mid-level winds from Fernanda had less effect on TS Greg than anticipated and the storm turned more westerly, keeping it over warmer waters longer.

Tropical Storm Greg blew up quickly. It was noted in a special bulletin from the NHC at 4AM MDT on 11/08 as tropical depression 7E. By 9AM MDT, the storm had reached Tropical Storm status. Circulating winds from Hurricane Fernanda are expected to push the storm into a more northerly motion over the next 36 hrs. Tropical storm Greg is not expected to achieve hurricane status, although that was the forecast for Fernanda as well, which formed in the same area two days ago. At 9AM MDT the NHC bulletin upgraded TD7E to Tropical Storm Greg, then located near 13.6N 110.5W or about 680 miles south of Cabo San Lucas. The storm was moving 290° at 11kts with sustained winds of 35kts and gusts to 45kts. Central barometric pressure was estimated at 1005Mb

Tropical Storm Greg never made landfall or threatened the Baja California peninsula.
