Hurricane Trudy is a category 1 hurricane 274 km SSW of Lazaro Cardenas, Michoacan, Mexico, moving northwest at 14 km/h. The latest reading, at 06:00 UTC on October 17, places the center at 15.7°N, 103.2°W, with sustained winds of 148 km/h, gusts of 170 km/h and a central pressure of 979 mb. Trudy’s winds increased from 139 to 148 km/h since the previous reading, while pressure fell from 982 to 979 mb, indicating that the storm is strengthening while remaining a category 1 hurricane. Trudy reached its strongest recorded intensity at category 3, with 194 km/h winds and 956 mb pressure, on October 16 at 06:00 UTC. Later readings on October 16 showed Trudy weaken to category 1. The available readings do not identify a water name for the current position.
No active watches or warnings.
October 11 — First recorded as a tropical depression
The first reading, at 06:00 UTC, recorded TWENTY-ONE as a tropical depression with winds of 28 km/h and gusts of 32 km/h. The centre was at 7.6°N, 88.0°W. The reading showed no movement; the following readings recorded a westward bearing of 261° at 22 km/h.
October 12 — Winds rise to 46 km/h
At 00:00 UTC, maximum sustained winds had increased from 28 km/h to 46 km/h, with gusts of 53 km/h. The reading also recorded a pressure of 1,010 mb. Winds remained at 46 km/h through the next readings, while pressure gradually fell to 1,008 mb by 18:00 UTC.
October 13 — Winds reach 56 km/h as pressure falls
At 12:00 UTC, the latest reading recorded winds of 56 km/h and gusts of 64 km/h, up from 46 km/h and 53 km/h 6 hours earlier. Pressure fell from 1,008 mb to 1,006 mb over the same interval. TWENTY-ONE remained a tropical depression, moving on a bearing of 300° at 15 km/h.
October 13 — Strengthens into a tropical storm
At 12:00 UTC, Trudy was a tropical depression with winds of 56 km/h, gusts of 64 km/h and pressure of 1,006 mb. By 18:00 UTC, the readings classified Trudy as a tropical storm, with winds of 65 km/h, gusts of 75 km/h and pressure of 1,005 mb.
October 15 — Strengthens into a category 1 hurricane
The October 15 06:00 UTC reading records Trudy as a category 1 hurricane, with winds of 120 km/h and gusts of 138 km/h. Pressure is 989 mb, down from 997 mb at 00:00 UTC, when winds were 102 km/h and Trudy was still a tropical storm.
October 16 — Strengthens to a category 2 hurricane
At 00:00 UTC on October 16, Trudy reached category 2 with winds of 157 km/h and gusts of 181 km/h. The reading recorded a pressure of 975 mb. Six hours earlier, Trudy was a category 1 hurricane with winds of 148 km/h and a pressure of 978 mb.
October 16 — Strengthens to a category 3 hurricane
At 06:00 UTC, Trudy's maximum sustained winds reached 194 km/h, up from 157 km/h six hours earlier, and gusts reached 223 km/h. Central pressure fell from 975 mb to 956 mb. The readings mark Trudy's rise from category 2 to category 3.
October 16 — Weakens to a category 1 hurricane
At 12:00 UTC, Trudy was a category 3 hurricane with 194 km/h winds, gusts of 223 km/h and a pressure of 956 mb. By 18:00 UTC, winds had fallen to 139 km/h, gusts to 160 km/h, and pressure had risen to 982 mb. The latest reading places Trudy 366 km southwest of Acapulco.
The readings show a gradual pressure decline, from 1,010 mb on October 12 at 00:00 UTC to 1,006 mb on October 13 at 12:00 UTC. Lower central pressure can accompany a strengthening tropical system, and here the wind record also rises: sustained winds increase from 28 km/h early on October 11 to 56 km/h in the latest reading. The observations do not record a change from tropical depression classification. Movement is generally westward, though the reported bearings vary; speeds range from 15 to 22 km/h after the initial stationary reading. The data do not include sea-surface temperature, wind shear or moisture measurements.
Turn on the tropical storm tracks layer in RainViewer to follow TWENTY-ONE’s recorded positions. Each track point is colored for the storm’s category at that moment: tropical depression is cyan, tropical storm is blue, category 1 is yellow, category 2 is amber, category 3 is orange, category 4 is red, and category 5 is dark red. The readings classify every point in this track as a tropical depression.
Compare the track points with their recorded times to see how the centre moved from 7.6°N, 88.0°W to 9.5°N, 96.1°W. The latest readings also show winds rising to 56 km/h and pressure falling to 1,006 mb. Check the RainViewer app on Google Play or the App Store to follow the recorded track and its updates.
The eastern Pacific hurricane season runs from May through November, with many tropical systems forming over warm ocean water. Thunderstorms can organize into a tropical cyclone when the surrounding atmosphere supports sustained circulation. Broad seasonal conditions explain why storms can form in this basin at this time of year, but they do not establish the conditions around TWENTY-ONE. The available readings give the storm’s position, wind, pressure and movement; they do not include measurements of ocean temperature, atmospheric moisture or wind shear.
Two eastern Pacific examples show how varied the outcomes of late-season storms can be. Hurricane Patricia reached Category 5 strength in 2015 before weakening before landfall. Hurricane Otis also reached Category 5 in 2023 and made landfall at that intensity. Those histories provide context, not a comparison of expected outcomes: TWENTY-ONE’s readings establish only its own observed classification, winds, pressure and track.
TWENTY-ONE is the designation used for this system in the supplied storm record. The record does not provide a separate personal name for it.
Sustained wind is the storm’s reported ongoing wind speed, while a gust is a brief, higher-speed burst. The latest reading lists sustained winds of 56 km/h and gusts of 64 km/h.
Central pressure is the air pressure measured near the centre of the storm. It is one measure used to describe a cyclone, but pressure alone does not establish its classification or impacts.
Meteorological agencies use names to identify storms clearly in forecasts and public communications. This record uses the designation TWENTY-ONE rather than a personal storm name.
