For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Eight-E, located well southwest of the Baja
California Peninsula.

South of Southern Mexico:
A trough of low pressure just offshore of the coast of Central
America is producing disorganized showers and thunderstorms.
Environmental conditions appear conducive for development, and a
tropical depression could form later this week while the system
moves generally west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...10 percent.

Additionally, an overnight ASCAT pass showed a well-defined circulation with peak winds near 30 kt. Given the improved convective organization and well-defined circulation, advisories are being initiated on Tropical Depression Eight-E. The initial intensity is set at 30 kt, based on a blend of the ASCAT pass and Dvorak current intensity estimates from both TAFB and SAB. The initial motion is estimated at 300/13 kt, along the southern side of a strong subtropical ridge. This ridge is forecast to remain in place through the 5-day period, steering the system generally west-northwestward for the entire forecast. A slightly more westward motion is possible by day 4 as the cyclone becomes more shallow and is steered within the low- to mid-level flow. The updated track forecast is close to the consensus aids. The system is forecast to steadily strengthen during the next couple of days as it moves over warm waters and through a moist, low-shear environment. It is expected to become a tropical storm on Monday and could approach hurricane strength between 36 and 60 hours. After that time, a gradual weakening trend is anticipated as the cyclone moves over sea surface temperatures below 26 degrees C and begins to entrain drier mid-level air within a more stable environment. Simulated satellite imagery from the global models supports this scenario, showing a reduction in deep convection as the system continues west-northwestward into the central Pacific basin. The forecast is slightly above the intensity guidance through 60 hours, then is in good agreement with the consensus aids thereafter.

The system has been devoid of deep convection overnight, with only an exposed swirl of low- to mid-level clouds remaining. The initial intensity is lowered to 45 kt, based on a blend of the latest subjective Dvorak estimates from TAFB and SAB and objective estimates from UW-CIMSS. Given the cool waters, dry and stable air, and strengthening west-southwesterly shear, no new organized convection is expected. Therefore, this will be the final advisory on the system as it has become post-tropical. Gil is expected to dissipate around midweek as it opens into a trough northeast of the Hawaiian Islands. The initial motion is estimated at 285/16 kt. The system is being steered by a low- to mid-level ridge to its north, and this general motion is expected to continue into tonight. A gradual decrease in forward speed is anticipated by Monday, followed by a turn toward the west as the shallow remnant low becomes steered by the low-level flow. The updated track forecast remains close to the previous advisory and continues to follow the tightly clustered guidance envelope.
