High pressure north of the islands will help maintain moderate to breezy trades through the week. Stable conditions will focus limited showers over windward and mauka areas through at least the middle of the week.
High pressure just north of the Hawaiian Islands will remain the dominant feature, maintaining stable moderate to breezy trades over the next several days. Bands of moisture continue to ride within these trades, bringing increased shower activity to windward and mauka areas, namely across Kauai and the Big Island through the early portions of this weekend. The remainder of the islands will see little rainfall as a brief period of drier conditions can be expected through much of today.
Trades gradually strengthen by the turn of the week as the aforementioned high just to the north of the islands builds and meanders a bit to the southeast. Conditions are expected to remain stable, focusing typical shower activity to windward and mauka areas through the early portion of the next week.
By the end of next week, excess residual moisture associated with Post-Tropical Cyclone Douglas may extend to the island chain by way of breezy trade wind flow. This may bring increased shower activity over initially windward and mauka locations and may spread further into leeward portions of the state toward the end of the forecast period.
Moderate to locally breezy trades will continue through the holiday weekend. Low clouds and showers will bring MVFR conditions to windward and mauka areas at times, with VFR conditions prevailing in leeward locales.
AIRMET Sierra remains in effect for mountain obscuration across windward sections of most islands. Conditions will likely improve later this morning.
AIRMET Tango remains in effect for moderate low level turbulence over and downwind of terrain of all islands. This AIRMET will likely continue through the weekend.
A high pressure ridge north of the Hawaiian Islands will keep trade winds blowing across the region through the week. A Small Craft Advisory (SCA) for the typical windy waters and channels around Maui and the Big Island continues through Monday. Minor fluctuations in wind speeds may allow for brief periods of additional zones to fall into the SCA coverage area over the next several days.
As the current small long period south swell fades, yet another overlapping moderate long period south-southwest swell will fill in today, boosting south shore surf heights to near High Surf Advisory levels Sunday and Monday. This swell will slowly fade from Tuesday through the middle of next week.
Surf along east facing shores will remain rough and choppy through the forecast period as moderate to locally strong trades hold. Surf along north facing shores will remain tiny into next week.
Small Craft Advisory until 6 PM HST Monday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.
