TROPICAL UPDATE

Disturbed area in Atlantic being investigated

ATLANTIC
The combination of a broad surface trough, tropical wave and an upper-level low are producing widespread showers and thunderstorms around 325 miles north-northeast of San Juan, Puerto Rico.

A tropical depression or storm may form from this complex system over the next day or so with upper-level winds forecast to become more favorable. The Hurricane Hunters are investigating this system to determine whether an area of low pressure has formed by that time.

Currently, the area of interest is moving off to the west-northwest around 20 mph. This west-northwest motion is expected to continue with a more northerly turn farther out in time.

Interests in the Turks and Caicos, Bahamas and along the U.S. East Coast should monitor this system closely to see what, if any, impacts it will bring later this week.

A broad low-pressure area has pushed inland over Central America with locally heavy rain. This system will be monitored for development once it reaches the eastern Pacific.

EASTERN PACIFIC
In the eastern Pacific, Tropical Storm Ignacio formed in the Eastern Pacific on Monday evening. It is located about 675 miles west-southwest of Cabo San Lucas, Mexico, and winds are near 50 miles per hour. Ignacio may strengthen a little more into Wednesday before running into cooler water, when it will begin to weaken. Ignacio is forecast to become a remnant low on Friday.

CENTRAL PACIFIC
Tropical Storm Hilda is located about 535 miles southeast of the Hilo, Hawaii, and winds have decreased to 50 miles per hour.
Hilda should resume a strengthening cycle by Wednesday and this will continue over the next several days, with Hilda forecast to become a hurricane late in the week.

Hilda is forecast to stay south of the Aloha State with no impacts other than a modest increase in east winds on the Big Island. However, residents should continue to monitor the progress of Hilda.
