Area Forecast Discussion National Weather Service Honolulu HI 907 PM HST Sun May 5 2024

SYNOPSIS
Breezy easterly trade winds will continue through Monday morning, decreasing to moderate levels from Monday afternoon onward. A passing weak upper level disturbance will drift over the islands through Monday enhancing passing showers. An unstable band of clouds and showers will drift into the islands on the trade winds, bringing another round of wet weather for all islands from Wednesday into Thursday.

DISCUSSION
Local island radar imagery show enhanced showers riding into the windward and mountain slopes of all islands this evening.
Satellite water vapor channel imagery continues to show a weakening upper level low slowly drifting from west to east across the island chain. This upper low will produce enough instability to keep wet trade winds in the forecast through Monday as it tracks eastward across the state.

A 1030 mb high pressure system 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 pressure system drifts eastward away from the Hawaiian Islands. Expect light to moderate easterly trade winds to continue through the rest of the week.

Wetter than normal conditions remain in the forecast for all islands through much of this week. Enhanced showers will continue into Monday as a weakening upper level disturbance drifts from west to east across the island chain. Tuesday will trend a bit drier. An unstable band of clouds and showers, remnants of an old East Pacific cold front, will drift into the islands on the trade winds producing wet weather for all islands from Wednesday into Thursday. An upper level trough sweeping in from north on Thursday and Friday will likely keep enhanced showers in the forecast into next weekend.

AVIATION
Breezy easterly trade winds will persist into Monday, with clouds and showers favoring windward areas. An upper low will move east across the islands tonight into Monday, along with an incoming band of showers, will result in increasing rainfall tonight for most windward areas. AIRMET Sierra for mountain obscurations will be possible later tonight for these areas. The easterly trades will begin to ease into the light to moderate range late Monday.

AIRMET Tango is in effect for moderate turbulence below 8000 feet downwind of island terrain due to the winds. Additionally, moderate turbulence aloft (FL280-FL380) is expected through tonight.

MARINE
A 1030 mb high centered over 800 nm north of the state is maintaining fresh to near gale force trade winds, and a Small Craft Advisory (SCA) remains in effect for all waters through tonight. Trades will gradually ease late tonight through Tuesday as the high moves eastward. As a result, the SCA is scheduled to be scaled back to the typically windy waters around the Big Island and Maui County by Monday morning and may be dropped entirely late Tuesday or Wednesday. Expect gentle to locally fresh trade winds to prevail Wednesday through Friday as a trough develops then lingers north of the islands. In addition, a few heavy showers will be possible tonight and Monday.

Pulses of south to southwest swell are due this week, with High Surf Advisory (HSA) conditions expected by Thursday. In the short term, the bulk of a south swell will be passing east of Hawaii.
The PacIOOS buoy off of Lanai is currently showing about a 2 feet 16 to 18 second swell this evening. This swell will continue to fill in tonight, south shore surf may peak around May average through early Monday, then decline late Monday through Wednesday.
Forerunners from a larger and longer lived south- southwest swell will arrive Wednesday, and surf is expected rise to the HSA level during the peak of the swell Thursday and Friday.

A pair of small northwest swells will move through over the next several days. As the current swell of around 2 feet at 12 to 13 seconds declines overnight, a reinforcing small swell of around 3 ft will fill in through Monday, peak Tuesday, then decline late Tuesday and Wednesday. Wind-driven waves of 8 to 9 feet at 9 seconds will maintain rough east shore surf above the May average into Monday. As trade winds decline over the next few days, these seas will gradually decline to around May average by Tuesday, then drop to below average for the rest of the week.
