Tropical Depression Two-C slows slightly as it continues towards Hawaii

HONOLULU (HawaiiNewsNow) – Newly formed Tropical Depression Two-C slowed slightly, but is continuing on a track toward the west-northwest and could bring heavy rain to parts of the state this weekend.

Two-C is expected to follow a path further south than Hurricane Lala, but could still bring the threat of more flooding rain and strong winds, especially for the hard-hit island of Hawaii.

At 11 p.m. Thursday, Two-C was located about 780 miles southeast of Hilo and was moving to the west-northwest at 10 miles per hour.

NWS said Two-C has changed little within the past several hours, and much of the deep convection remains positioned north of the low-level circulation.

A gradual turn toward the west is forecast later in the weekend as the ridge builds to the north of the system. Track guidance remains in generally good agreement, although some cross-track spread persists as the cyclone approaches and passes south of the Hawaiian Islands this weekend and into early next week.

The tropical depression had maximum sustained winds of 35 miles per hour with higher gusts. It is expected to strengthen into a tropical storm later Thursday; when it does, it will get the Hawaiian name “Moke.”

Potential threats

Rain

The tropical depression is expected to produce rainfall totals of 5 to 10 inches with maximum amounts of 15 inches across Hawaii Island. This rainfall could cause dangerous flooding in areas already saturated by the catastrophic rainfall from Hurricane Lala.

Rainfall totals of 1 to 2 inches with maximum amounts of 3 inches are expected for East Maui.

For the rest of the islands, 1 to 2 inches of rainfall is expected this weekend and early next week.

This rainfall may produce life-threatening flooding and mudslides, especially in steep terrain and over areas that were affected recently by Lala.

Surf

Swells generated by the depression are expected to affect portions of the Hawaiian Islands this weekend, and could cause life-threatening surf and rip current conditions.
