Tuesday 7th April 2026
Today light to moderate southeast winds and widely scatterly rain increasing to breezy winds and frequent heavy rain and possible thunderstorms later today into early Wednesday.
Wednesday and Thursday light southerly winds and humid with periods of heavy rain possible.
Friday stormy with gusty south winds and frequent heavy rain and thunderstorms.
Saturday and Sunday light southerly winds and humid with periods of heavy rain possible.
The southerly flow near the surface and southwesterly flow aloft could spread VOG over much of windward Hawaii island.
A trough is passing by to our northwest today bringing unsettled conditions and pulling tropical moisture over us from the south. The trough moves away on Wednesday, but deep moisture remains in place. With light winds on Wednesday and Thursday afternoon thunderstorms are possible.
A stronger trough (200mb) and associated front move towards us on Friday brings stronger winds, deeper moisture, colder air aloft, diverging flow aloft and a boundary along which to focus the heaviest activity.
In other weather news 90W is looking structurally close to a closed circulation (satellite animation) and could be upgraded if the central pressure drops. This is 1,300 miles farther east than the previous April storm record. The warm sea surface temperatures under 90W are part of a region of warmer waters that is also the source for the extreme moisture that will be flowing over us for the next week.
