Eastern Pacific Tropical Weather Outlook
Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Lala, located several hundred miles north of Kure Atoll, and
on Tropical Storm Iselle, located several hundred miles west of the
southern tip of the Baja California Peninsula. The National
Hurricane Center has issued the last advisory on the Remnants of
Julio, located well west of the southern tip of the Baja California
Peninsula.
Central East Pacific:
A tropical wave located well to the south of southwestern Mexico is
producing a large area of showers and thunderstorms. This system is
gradually becoming better organized, and environmental conditions
appear favorable for continued development. A tropical depression is
expected to form in the next two or three days while it moves
generally west-northwestward at 10 to 15 mph, well offshore of
Mexico.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 7 days...high...90 percent.
Western East Pacific:
A weak and small area of low pressure located well to the
east-southeast of the Hawaiian Islands is producing some

Tropical Storm Iselle is near 21.0N 121.8W at 2 PM PDT, moving west-northwest at 8 kt. Estimated minimum central pressure is 994 mb. Maximum sustained wind speed is 50 kt with gusts to 60 kt. Iselle will continue to move west-northwestward and away from the area waters, while gradually weakening, reaching near 21.3N 123.0W tonight, and near 21.8N 124.7W midday Wed. Large S-SW swell from Iselle will continue to move through the Baja waters through early Wed before quickly subsiding. Elsewhere, fresh northerly gap winds will continue to pulse to strong speeds across Tehuantepec region during the overnight and early morning hours through the upcoming weekend, with seas occasionally building to 8 ft. Looking ahead, another tropical wave and developing low pressure area will follow a similar trajectory as Iselle, Thu through the weekend, and impact the outer offshore waters near the Revillagigedo Islands within increasing winds and seas. A tropical depression could form late this weekend or early next week while it moves westward to west- northwestward at 10 to 15 mph well offshore of southern Mexico.
Variable winds less than 5 kt, becoming NW to N 10 kt late. Seas 3 to 5 ft. Period 16 seconds. Scattered showers and isolated tstms through the night.
N to NE winds 10 kt. Seas 3 to 5 ft. Period 16 seconds. Scattered showers and isolated tstms through the night.

Understanding the Forecast Models, swell forecasts and Banderas Bay weather Learn more
GFS
NOAA's global forecast model. It is useful for broad weather trends, wind patterns and longer-range planning.
ECMWF
A widely used European global model. Comparing ECMWF with GFS can help show how much uncertainty exists in a forecast.
Wave Models
Marine models forecast both locally generated wind waves and longer-period swell arriving from distant weather systems.
Banderas Bay
Mountain terrain and daytime heating often produce a northwesterly afternoon thermal. Broad global models can underestimate this very local wind pattern.
