Wali has been downgraded to a Tropical Depression. At 11 a.m. HST, the center of Tropical Depression Wali was located near latitude 16.0 north, longitude 144.0 west. The depression is moving toward the northwest near 13 mph, 20 km/h, and this motion is expected to continue until Wali dissipates within 24 hours.

Maximum sustained winds are near 35 mph, 55 km/h, with higher gusts. Wali is expected to become a post-tropical remnant low within 12 hours and dissipate within 24 hours.

The estimated minimum central pressure is 1007 mb, 29.74 inches.

The National Weather Service in Honolulu has issued a Flash Flood Watch for all Hawaiian Islands from 6 p.m. Saturday through 6 p.m. Monday (July 19-21).

The heavy showers and thunderstorms associated with the system which is now Tropical Storm Wali is expected to reach the Big Island and Maui Saturday night.

Campers and hikers should avoid low lying flood prone areas. People should stay away from streams, drainage ditches and low lying areas prone to flooding. The rainfall and runoff will cause hazardous driving conditions due to ponding, reduced visibility and poor braking action.

Do not cross fast flowing or rising water in your vehicle or on foot. Turn around, don’t drown.
