Early warning forecast: Stormy weather to remain today and calmer on Tuesday

HONOLULU (HawaiiNewsNow) – The first day of a weather alert has been issued as thunderstorms, strong winds and possible flooding threaten the state.

The disturbance near Maui County will act as the center of cloud and rain development across the islands as it slowly moves west into Monday.

A strong upper-level low in the west will destabilize the atmosphere and bring heavy rain that can cause flooding.

Several weather warnings, including a flash flood watch, are in effect for the entire island until 6:00 p.m. Monday.

With the ground already saturated, any additional rain could be a major concern, with weather associated with poles and rocks, downed trees and flowing streams.

Initially, most of the rain will likely affect Kauai and Hawai’i Island on Monday, with heavier pockets later in the Mauka and Windward areas.

The public is advised not to drive through fast-moving water and flooded areas.

The potential for heavy downpours will gradually diminish Monday night and Tuesday as winds lighten for most of the week. Trade winds will return by the end of the week.

A High Surf Advisory (HSA) has been issued for most of the northern and western beaches from Kauai to Maui, as well as the eastern beaches of Kauai.

Another moderate northwesterly swell is expected midweek along with a small pulse of southerly swell.
