WEATHER WATCH: Periods of heavy rain showers are likely to continue across the islands today; Flood Watch issued for most of the state
Overview
An unseasonably cold upper-level low has dipped down from the north-central Pacific overnight, bringing moisture and instability to the region which will likely result in periods of heavy rain showers, along with isolated to scattered thunderstorms, throughout the day today.
The low is expected to settle over Kauai by midday and then slowly progress eastward this evening and weaken overnight.
Flood Watch
A Flood Watch is currently in effect for all islands except for Hawaiʻi.
This watch is in effect through this afternoon, but could be extended into the overnight hours for some areas depending on the rate at which this system progresses eastward and weakens this evening.
Flood-prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff.
