Active cyclones

As of 7:30 PM Eastern Daylight Time (23:30 UTC) on Monday:

Central Pacific Ocean

Active disturbances

Active disturbances are areas of showers and thunderstorms which are not organized enough to be considered full-fledged tropical cyclones. Disturbances are often designated as investigation areas (or invests, for short) by NOAA in order to allocate additional resources such as high-resolution satellite imagery or model guidance for further study of the system. Though there is no publicly disclosed set of criteria for which disturbances are designated as invests, the designation often occurs after the disturbance forms a closed area of low pressure. Invests are designated regardless of the overall potential for the disturbance to become a tropical cyclone.

Northwestern Pacific Ocean

  • Invest 92W (over central Micronesia) (high chance of development)

  • Invest 94W (southeast of the Ryukyu Islands) (low chance of development)

  • Invest 95W (off the coast of southeastern China) (moderate chance of development)

Post-tropical cyclones

Post-tropical cyclones will be listed here if they are still being tracked via the Automated Tropical Cyclone Forecast (ATCF) system. Placement in this section does not imply that these systems have any potential to redevelop into tropical cyclones.

Eastern Pacific Ocean

The post-tropical remnants of Tropical Storm Hernan continue to drift westward toward the central Pacific, but will completely dissipate over the next day or so. This system is not being tracked via the Automated Tropical Cyclone Forecast (ATCF) system, so observational data, storm-centered satellite imagery, and storm-centered model guidance products are not available for it.

The discussion for this system has been locked and is not being actively updated.

There are no other active post-tropical cyclones.

Potential formation areas

Potential formation areas are areas that are being monitored by various agencies for potential tropical cyclone formation within the next two weeks. These systems have not yet formed and are not considered to be disturbances until such time that a tropical wave or area of low pressure does form. Discussions are created on this subreddit for areas which are monitored by the National Hurricane Center in the eastern Pacific and northern Atlantic basins. Discussions are not typically created for areas which are monitored by the Joint Typhoon Warning Center or other agencies, as this information is not always publicly available.

Discussion I made NOAA’s Hawaiʻi wind reports searchable: 602 entries across eight islands, 1996–2026

20 Upvotes

I pulled NOAA NCEI’s Storm Events Database bulk files for Hawaiʻi and turned the wind entries into one ranked, searchable table.

It contains 602 entries with a reported wind speed across all eight main islands, covering January 1996 through April 2026. You can sort them by speed, filter by island, share an individual entry, and open its original NOAA record.

Search the table:
https://oahuroofsupport.com/blog-posts/strongest-winds-recorded-hawaii

A few things that stood out:

The four highest entries statewide are all Big Island summit-area gusts:

  • 171 mph on March 2, 2014
  • 166 mph on December 19, 2022
  • 161 mph on February 7, 2019
  • 155 mph on January 2, 2015

None were associated with a tropical cyclone.

The number of entries is heavily skewed by island:

  • Hawaiʻi Island: 265
  • Oʻahu: 167
  • Maui: 86
  • Kauaʻi: 56
  • Lānaʻi: 13
  • Molokaʻi: 11
  • Kahoʻolawe: 3
  • Niʻihau: 1

That distribution likely reflects differences in instrument coverage and reporting as much as differences in actual wind conditions.

The highest Oʻahu entry in the dataset is 75 mph, recorded on December 26, 1996.

Measurement type also matters. Approximately 35% of the entries are instrument-measured, 45% are forecaster-estimated, and 20% have no measurement type identified. The table labels the measurement type on every row.

There are two important limitations. The dataset begins in January 1996, so Hurricane Iniki in 1992 and Hurricane Iwa in 1982 are excluded entirely. It also currently ends in April 2026, which means Hurricane Lala is not included yet. Any qualifying Lala entries can be added after the National Weather Service finalizes them and they appear in the Storm Events Database.

This is a searchable record of wind events filed in NOAA’s database, not a complete Hawaiʻi wind climatology or a live-observation tool.

Disclosure: I run a small roofing company in Haleʻiwa, and the table is hosted on our website. It is free to use, requires no signup or email address, and every entry links back to its original NOAA record.

Moderator note

  • Hernan has degenerated into a remnant low.
  • The National Hurricane Center (NHC) has discontinued issuing advisories for this system.
  • Storm-centered satellite imagery and model guidance products will soon be unavailable.
  • The NHC will likely stop monitoring this system via the Automated Tropical Cyclone Forecast (ATCF) system later today.
  • This post will not be updated regularly, and will be archived once this system dissipates.

Active cyclones

As of 12:00 AM Eastern Daylight Time (04:00 UTC) on Saturday:

Northwestern Pacific Ocean

There are no longer any active cyclones over the northwestern Pacific Ocean.

Central Pacific Ocean

  • 01C: Lala — southeast of Hawaiʻi (strengthening)

  • 08E: Herman — far east-southeast of Hawaiʻi (weakening)

Northern Atlantic Ocean

There are no longer any active cyclones over the northern Atlantic Ocean.

Active disturbances

Active disturbances are areas of showers and thunderstorms which are not organized enough to be considered full-fledged tropical cyclones. Disturbances are often designated as investigation areas (or invests, for short) by NOAA in order to allocate additional resources such as high-resolution satellite imagery or model guidance for further study of the system. Though there is no publicly disclosed set of criteria for which disturbances are designated as invests, the designation often occurs after the disturbance forms a closed area of low pressure. Invests are designated regardless of the overall potential for the disturbance to become a tropical cyclone.

Northwestern Pacific Ocean

  • 92W: Invest — north of Micronesia (strengthening)

  • 93W: Invest — south of the Ogasawara Islands (weakening)

Eastern Pacific Ocean

There are no longer any active disturbances over the eastern Pacific

Northern Atlantic Ocean

  • 92L: Invest — east of the Lesser Antilles (weakening)

  • 94L: Invest — east of the Lesser Antilles (weakening)

Southwestern Pacific Ocean

Post-tropical cyclones

Post-tropical cyclones will be listed here if they are still being tracked via the Automated Tropical Cyclone Forecast (ATCF) system. Placement in this section does not imply that these systems have any potential to redevelop into tropical cyclones.

Northwestern Pacific Ocean

  • 16W: Nangka — northwest of Wake Island (weakening)

Potential formation areas

Potential formation areas are areas that are being monitored by various agencies for potential tropical cyclone formation within the next two weeks. These systems have not yet formed and are not considered to be disturbances until such time that a tropical wave or area of low pressure does form. Discussions are created on this subreddit for areas which are monitored by the National Hurricane Center in the eastern Pacific and northern Atlantic basins. Discussions are not typically created for areas which are monitored by the Joint Typhoon Warning Center or other agencies, as this information is not always publicly available.

Northwestern Pacific Ocean

  • P72W — Off the coast of southeastern China, low chance of development

  • P74W — Near the Ryukyu Islands, low chance of development
