Tropical System May Threaten Hawaii Late This Week

Rain and gusty winds may threaten Hawaii later this week as a tropical disturbance, currently on the verge of becoming a tropical depression or storm, tracks toward the islands.

"Warm water and low wind shear will contribute to some strengthening this week as the tropical disturbance tracks toward Hawaii," said AccuWeather.com meteorologist Evan Duffey.

Residents and travelers to Hawaii should pay close attention to the track and strength of this system, particularly those on the Big Island.

Should this system become a tropical storm, it will be named Ana.

"Traditionally, tropical systems struggle to maintain strength as they approach Hawaii from the Southeast," said Duffey. "However, abnormally warm water south of Hawaii could support an organized tropical system surviving into Hawaii."

AccuWeather.com meteorologists think at the very least, a surge in clouds, rain and even gusty winds will reach the Big Island later Friday night and Saturday.

Numerous showers and downpours will then expand into the remainder of the islands throughout the upcoming weekend, including in Honolulu. Clouds and rain may linger into early next week as the system nearly stalls over the islands.

The rain could pose a flash flood threat, resulting in some washed-over roads or local landslides. This will mostly depend on whether an organized tropical system will reach Hawaii.

This latest tropical threat for Hawaii follows Iselle's historic landfall on the Big Island earlier this year.

Iselle originated in the eastern Pacific, but a future Ana would be the second formation in the central Pacific. Wali formed in July, but failed to reach Hawaii as a tropical system.
