Discussion

Latest satellite data indicates unstable conditions diminishing as the trough that brought considerable flash flooding yesterday moves further southeast. Fair weather has taken over and will persist through Thursday. This means limited showers and light winds are possible for this duration.

By Friday, a strong high pressure system over New Zealand will extend towards the Samoa Island chain. This feature will shift winds south and may strengthen it up to 20 mph through Saturday. Additionally, south winds could usher in cool air from the south. As the high moves east on Sunday, this will allow for a weak trough to the northeast to move in the area Sunday night. Expect an uptick in showers Sunday night through Tuesday until the trough exits the region thereafter. However, the risk for flash flooding from this trough is low at this time.

Marine

Surf and wind have subsided in the area, which prompted a cancellation for the high surf advisory. However, as waves continue between 6 to 8 feet, a small craft advisory will hold until tonight. Expect ideal ocean conditions Wednesday through Thursday, before another swell moves in from the south over the weekend.
