Environmental conditions are expected to be conducive for gradual development, and a tropical depression is likely to form later this week while the low moves westward to west-northwestward at 15 to 20 mph. Interests in the Windward Islands, the southeastern and south-central Caribbean Sea, as well as the northern coast of South America, should monitor the progress of this system. * Formation chance through 48 hours...low...30 percent * Formation chance through 5 days...high...90 percent $$ Forecaster Pasch

For the eastern North Pacific...east of 140 degrees west longitude:
The National Hurricane Center is issuing advisories on Tropical
Depression Eighteen-E, located well southwest of the southern tip of
the Baja California peninsula.
An area of low pressure located near the Central Pacific basin about
1200 miles east-southeast of the Big Island of Hawaii continues to
produce disorganized showers and thunderstorms. Environmental
conditions are expected to be conducive for gradual development of
this system later this week. This low is expected to move little
during the next day or two and then turn northward.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...medium...50 percent

Tropical Depression EIGHTEEN-E Forecast Discussion Number 3
Issued at 800 PM PDT SUN SEP 25 2016 000 WTPZ43 KNHC 260243 TCDEP3 TROPICAL DEPRESSION EIGHTEEN-E DISCUSSION NUMBER 3 NWS NATIONAL HURRICANE CENTER MIAMI FL EP182016 800 PM PDT SUN SEP 25 2016 The cloud pattern of the depression has not changed much during the last several hours. The center of the system is partially exposed on the west side of a convective band. Satellite images also show a pronounced dry slot to the west and northwest of the center. The Dvorak classifications remain T2.5/35 kt from TAFB and T1.5/25 kt from SAB, and based on these estimates, the initial wind speed is held at 30 kt. Some slight strengthening is possible overnight or on Monday while the system remains over warm water and in an environment of light to moderate shear. After that time, the environment should become less conducive with southwesterly shear increasing to more than 20 kt in about 24 hours, which will likely end the opportunity for strengthening. The system is forecast to cross the 26-deg-C isotherm in 36 to 48 hours, and as a result, it should become a remnant low by day 3. The global models show the remnant low dissipating by the end of the forecast period, and that is reflected in the official forecast. The new intensity forecast is a little lower than the previous one and is in good agreement with the latest intensity model consensus. The center of the depression has wobbled a bit to the west of the previous track, and the current motion estimate is 345/6 kt. A large cut-off mid- to upper-level low over northwestern Mexico is expected to drift southwestward during the next day or two. This should cause the system to turn north-northeastward to northeastward on Monday, and continue in that general direction through mid-week. Once the system becomes a shallow remnant low, a turn to the west-northwest is predicted, following the low-level trade wind flow. The NHC track forecast is not too different from the previous one, and is in best agreement with the GFS ensemble mean and a consensus of the GFS and ECMWF models.
