Synopsis

The cold front has dissipated into a trough and remains northwest of the Hawaiian Islands this evening. High pressure will build in from the north and allow the trade winds to strengthen from Monday through Wednesday. Brief passing showers will favor windward and mountain areas in the overnight to early morning hours through Wednesday and then over southeastern slopes and island interior sections from Thursday onward. Winds will weaken and veer slightly from a more east-southeast direction from Thursday on into the weekend. Shower activity will remain limited during this time period.

Short term update

The large band of high level cirrus clouds and mid level alto stratus clouds currently over the islands will continue to slowly diminish through Monday. The cold front approaching the islands has stalled and diminished into a trough just northwest of the island of Kauai.
Trade winds blow into the region and strengthen into the moderate to locally breezy range from Monday through Wednesday. A slight decrease in wind speeds and a shift from a more east- southeast direction remains in the forecast from Thursday onward as another cold front approaches the islands from the northwest, weakening and lifting the ridge north of the state. Local scale sea breeze winds will develop along terrain sheltered slopes of each island as the large scale winds weaken. Limited shower activity will prevail into next weekend with only brief showers possible.
The afternoon forecast looks good. No evening updates.

Previous discussion

Issued at 302 PM HST Sun Mar 1 2026.
Expectations for this afternoon remain on track. The boundary upstream of Kauai has made little to no forward progress today, sea breezes have struggled to establish owing to abundant high clouds, and showers southwest of Kauai and Oahu have essentially remained in place while stratiform elements peel off to the northeast. In addition, regenerating showers over Windward Oahu have dissipated in response to backing low-level flow. All told, an uneventful, cloudy, and mostly dry day across the state. Going forward, building heights over the N Central Pacific will maintain strengthening, but progressive high pressure at the surface. This in turn ensures the return of trades tonight which then become breezy during mid-week. Winds diminish slightly by late week as trades veer to ESE in advance of another round of upstream height falls. Typical trade wind weather anticipated throughout this time with showers focused windward and mauka. High clouds gradually clear from west to east Monday into Tuesday before exiting the area altogether by Wednesday.

Aviation

A weakening stationary boundary will allow for abundant high clouds and relatively light land/sea breezes to prevail across most TAF sites. This front will also allow for disorganized showers across Kauai and Oahu tonight, however confidence was on the lower end based on weather model guidance, so made use of VCSH and PROB30 where rain chances were felt to be the highest. MVFR conditions may prevail under shower activity, otherwise VFR is expected across most sites for the period.
AIRMET Tango remains in effect across the islands due to upper- level turbulence from FL200-400 due to this front, with conditions expected to improve into tomorrow as this system continues to weaken. Patchy mountain obscuration may occur due to the presence of this front, however observations and webcams suggest that the threat is not widespread enough to warrant an AIRMET at this time. Light icing is also possible in cloud layer 120-180.

Marine

Issued at 302 PM HST Sun Mar 1 2026.
A dissipated front will linger into Monday just northwest of the area. Fresh to locally strong easterly trades will build in by Tuesday as surface ridge strengthens to the north. Winds will maintain strength but veer east southeast towards the end of the week as another system approaches from the west.
Surf along north and west-facing shores will be above seasonal average as a northwest swell (310 degrees) is expected to impact through Monday. Surf should remain small though the week with a small northwest bump expected next weekend.
Surf along exposed east-facing shores will be a bit elevated due to a short-to medium-period northeast (40 degrees) swell, then decline Tuesday. However, period and choppy conditions are expected to return by Tuesday as fresh trade winds redevelop and expand upstream of the state.
Surf along south-facing shores will remain near the seasonal average into March.

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.
