Synopsis

Light to moderate trades will persist today, with a band of enhanced moisture bringing some showery weather to portions of the state this morning. Drier conditions are expected this afternoon, however sea breeze development will allow for a few showers to develop in leeward areas this afternoon. The trades will ramp back up tonight, then hold at moderate to breezy levels Sunday through Thursday. Rather dry conditions will prevail Sunday through Wednesday, with a trend toward more showery conditions late next week.

Discussion

Currently at the surface, a ridge of high pressure located around 225 miles north of Kauai is producing light trade winds with land breezes present in many areas across the island chain. Infrared satellite imagery shows mostly cloudy conditions across much of the state, with a few areas around the Big Island seeing a bit less cloud cover. Radar imagery shows scattered showers moving into windward areas, with the coverage highest from Oahu to Big Island where leeward areas are seeing some shower activity as well. Main short term focus revolves around trade wind trends and rain chances during the next couple days.
The ridge of high pressure north of the islands will remain nearly stationary today, keeping light to moderate trades in place and allowing some sea breeze development in leeward areas. The ridge will lift northward late today through the remainder of the weekend, allowing the trades to gradually increase to moderate and breezy levels by Sunday, and hold at these levels through much of next week.
As for the remaining weather details, an area of enhanced moisture will bring some showery weather to windward areas and send some of these showers into leeward locales through the morning hours today. Drier conditions should develop by afternoon, with a few showers developing over leeward terrain with the assistance of localized sea breezes. Rather dry conditions are then expected tonight through the middle of next week, with mid-level ridging and stronger trades keeping light showers confined primarily to windward and mauka areas. Mid-level ridging begins to break down late next week, which should bring an increase in trade wind showers to the island chain.

Aviation

Light to moderate easterly trade winds will persist through this afternoon. Flow should be light enough to bring nighttime land breezes and daytime sea breezes over each island. Clouds and showers will favor windward and mauka areas through the period, with some afternoon development over leeward interior areas. Brief MVFR ceilings and visibility will be possible in showers, especially over windward portions of the smaller islands, but expect VFR conditions to generally prevail at the TAF sites.
AIRMET Sierra is currently in effect for mountain obscuration above 2500 feet for north thru southeast sections of Kauai, Oahu, Molokai, and Maui.

Marine

Trades will steadily increase over the weekend as the surface ridge nearby lifts northward and strengthens. The strongest winds are expected over the windier waters and channels around Maui County and the Big Island beginning tonight, which will require a Small Craft Advisory. Little change in wind speed is expected through the first half of next week.
Surf along south-facing shores will remain up through Monday as a medium period south-southwest swell moves through. The nearshore and offshore buoy observations reflect this swell and show the peak energy holding within the 13-14 second bands this morning. A downward trend is expected Tuesday through midweek, with mainly background southerly energy expected. A similarly sized south- southwest swell is possible next weekend.
Surf along north and west-facing shores will trend up late Sunday through Monday as an out-of-season, small north-northwest swell arrives. This trend with small north-northwest pulses could persist through a good portion of the upcoming week due to broad low pressure positioned far north of the state near the Aleutians.
Surf along east-facing shores will pick up slightly later this weekend through early next week as the trades increase. Although confidence remains low being so far out in time, guidance is hinting at a medium- to long-period easterly swell arriving late next week through next weekend due to the uptick in tropical activity across the far eastern Pacific.
Higher-than-predicted water levels combined with near-peak monthly tides and a decent south swell moving through could lead to minor coastal flooding/runup impacts through the weekend. The best chance for coastal impacts will occur during the afternoon hours around the peak daily high tide cycles.

Flames engulf van on H-1 Freeway near Punchbowl

HONOLULU (HawaiiNewsNow) – Firefighters responded to a vehicle fire on the H-1 Freeway late Friday night.

The Honolulu Fire Department said the fire was reported around 10:40 p.m. on the H-1 eastbound, after the Kinau Street exit.

Witnesses told Hawaii News Now flames rose higher than the concrete barrier separating the eastbound and westbound lanes.

One unit with four personnel responded and quickly brought the fire under control.

The fire was extinguished, and the responding unit was cleared from the scene by 11:22 p.m.

No other details were immediately available.

Volcano Watch: Think Hawaii has many volcanoes? Think again, says El Salvador – West Hawaii Today

Volcano Watch: Think Hawaii has many volcanoes? Think again, says El Salvador – West Hawaii Today

This past March, a team of U.S. Geological Survey scientists — two of whom travelled from Hawaii — visited El Salvador in Central America for volcanological field studies and a workshop on lava flow hazards. Exchanges like this help to improve awareness of volcanic hazards in other countries, and they enable the USGS to better understand volcanoes in our own backyard.

El Salvador is the smallest country in Central America, sitting on the Pacific coast and measuring slightly larger than all the Hawaiian Islands combined.

However, the eight main Hawaiian Islands are comprised of only 15 volcanoes above sea level; El Salvador, on the other hand, has over 200! And that’s with a population of about 6 million people, about four times as many as Hawaii.

There are numerous volcanoes in El Salvador because it sits along the Central American volcanic arc, rather than atop a hotspot like Hawaii. Volcanic arcs form where an oceanic tectonic plate subducts beneath either a continental plate or another oceanic one; the ocean crust triggers melting as it dips into the Earth’s mantle, creating magma that rises to the surface through the overlying plate. Though El Salvador has five larger volcanoes with historical eruptions, numerous fault lines allow magma from the subduction zone to emerge just about anywhere. This has resulted in hundreds of smaller volcanoes, most of which have erupted only once.

Volcano monitoring in El Salvador is handled by the Ministerio de Medio Ambiente y Recursos Naturales (MARN). In addition to tracking the weather and other natural hazards, a small team of volcanologists works to study the geological and geophysical dynamics of the country’s volcanoes, while maintaining a watchful eye for signs of unrest. The stratovolcanoes of Santa Ana and San Miguel have both erupted in the past 25 years, but even more destructive events have occurred in the not-too-distant past: San Salvador volcano sent a lava flow into presently developed areas in 1917, and Ilopango caldera had a regionally devastating eruption in the year 431.

USGS, through its Volcano Disaster Assistance Program (VDAP), has maintained a collaborative relationship with MARN for decades. Co-funded by the U.S. Department of State, VDAP has supported numerous technical investigations and monitoring projects at volcanoes in developing countries around the world. Meanwhile, many MARN volcanologists have even studied in the United States as part of the Center for the Study of Active Volcanoes (CSAV) course held every summer in Hawaii and Washington state.

In recent years, VDAP’s relationships in El Salvador have focused on geologic projects to describe the eruptive history and hazards of Santa Ana volcano and a broader effort to assemble a national “volcano atlas,” which will include locations, compositions, and — hopefully — approximate ages for the more than 200 volcanic vents in the country. Such knowledge will enable more accurate understanding and delineation of hazards associated with their eruptions, which are both explosive (ash-producing) and effusive (lava flow-producing).

The field work in March served both projects. Dozens of samples were collected to correlate and date eruptive deposits across Santa Ana, including three sediment cores from coastal mangroves and a montane bog that may contain distant ashfall from the volcano. Reconnaissance visits were also made to several monogenetic (single-eruption) vents scattered around western El Salvador to assess their genesis and ages.

Finally, VDAP sponsored a weeklong workshop on lava flow hazards and monitoring for MARN staff and partner agencies. Since El Salvador’s last lava flow erupted in 1917, none of the current team have responded to such an event. USGS scientists from the Hawaiian, Cascades, and Alaska Volcano Observatories discussed their experiences and best practices developed during recent eruptions at Kilauea and Mauna Loa in Hawaii, as well as Great Sitkin and Pavlof in Alaska.

While the USGS scientists learned plenty about volcanism in El Salvador during this trip, it also provided key insights to bring home to our own volcanoes. Explosive eruptions in Hawaii are relatively rare, but the ability to correctly interpret their deposits is critical to understanding potential future hazards. Additionally, the more distributed nature of volcanoes in El Salvador has led to interesting interactions between lava flows and their more-weathered depositional environments, not unlike some of Hawaii’s older volcanoes: Hualalai, Mauna Kea, and Haleakala. We thank MARN for the opportunity to visit and study their country’s volcanoes.

Volcano
activity updates

Kilauea has been erupting episodically within the summit caldera since Dec. 23, 2024. Its USGS Volcano Alert level is ADVISORY.

Episode 46 of summit lava fountaining happened for nine hours on May 5. Summit region inflation since the end of episode 46 indicates that another fountaining episode is possible but more time and data is needed before a forecast can be made. No unusual activity has been noted along Kilauea’s East Rift Zone or Southwest Rift Zone.

Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL.

HVO continues to closely monitor Kilauea and Mauna Loa.
