A portion of the subtropical jet stream remains near the islands this afternoon, but is forecast to weaken over the next day or so.

Winds at the Big Island Summits have been borderline advisory level today, but the overall trend this afternoon has been down.

Therefore, the Wind Advisory for the summits has been cancelled.

At the surface and lower elevations, a 1029 mb high remains far north of the island chain and will continue to produce breezy easterly trade winds across the state into Monday.

By Monday afternoon, trade wind speeds transition to more moderate levels as the high moves off to the east.

Expect moderate easterly trade winds to continue through the rest of the week.

Enhanced showers will continue through Monday night as the weakening upper level disturbance swings through the island chain from west to east.

Showers will be heaviest and most widespread over windward areas and during the overnight and early morning hours.
