Karina was a category 4 hurricane over open water with nothing near it, moving at 20 km/h on a heading of 281° in its final reading. The reading at 2026-09-02 12:00 UTC placed Karina at 18.7, -132.3, with sustained winds of 232 km/h, gusts of 267 km/h and central pressure of 940 mb. Karina held category 4 strength from the previous reading, with the same wind speed, gust speed and pressure. The storm reached its strongest recorded intensity at 06:00 UTC on September 2, when winds also measured 232 km/h and pressure measured 940 mb. Karina began as a tropical depression on August 25, became a tropical storm on August 27, reached category 1 hurricane strength on August 30 and rapidly strengthened to category 4 on August 31. The record has ended, so RainViewer will not add further readings.
No active watches or warnings.
August 25 — Forms as a tropical depression
Karina begins the record as a tropical depression with 28 km/h winds, 32 km/h gusts and 1,008 mb pressure. The first reading places the centre at 8.6°N, 103.8°W, with no nearby place or named water in the reading. Karina remains nearly stationary at first, then starts moving west.
August 27 — Strengthens into a tropical storm
Karina becomes a tropical storm at 18:00 UTC on August 27, with sustained wind of 74 km/h, gusts of 85 km/h and pressure of 1,001 mb. The centre is at 10.8°N, 111.5°W. Movement has turned toward the northwest at 21 km/h after several days of generally westward motion.
August 30 — Reaches category 1 hurricane strength
Karina reaches category 1 hurricane strength at 06:00 UTC on August 30 with 120 km/h winds, 138 km/h gusts and 983 mb pressure. Six hours later, wind reaches 130 km/h and pressure falls to 980 mb. By 18:00 UTC, wind is 148 km/h and pressure is 973 mb.
August 31 — Rapidly strengthens to category 4
Karina reaches category 3 strength at 00:00 UTC on August 31 with 204 km/h winds and 954 mb pressure. Six hours later, it becomes a category 4 hurricane with 222 km/h winds and 945 mb pressure. The centre is at 17.2°N, 124.0°W, moving west-northwest at 13 km/h.
September 2 — Records peak intensity
Karina reaches its strongest recorded wind at 232 km/h on September 2 at 06:00 UTC, with gusts of 267 km/h and pressure of 940 mb. The latest reading, six hours later, keeps the same wind, gust and pressure values. The centre is at 18.7°N, 132.3°W, moving west-northwest at 20 km/h.
Karina intensifies steadily from 28 km/h winds and 1,008 mb on August 25 to 232 km/h and 940 mb on September 2. The largest pressure fall occurs during the transition from tropical storm to major hurricane: pressure drops from 987 mb at 18:00 UTC on August 29 to 945 mb by 06:00 UTC on August 31. A lower central pressure generally corresponds to a stronger tropical cyclone. Wind rises alongside the pressure fall, reaching category 4 strength within 24 hours of the first category 1 reading.
Karina’s movement is initially slow, then becomes faster and more variable in direction. The system travels mainly west from August 25 through August 27, turns northwest from August 27 through August 29, and shifts back toward west-northwest afterward. Forward speed reaches 27 km/h on August 28, slows to 13 km/h during the first category 4 readings, and is 20 km/h in the latest reading. The final two readings show unchanged wind and pressure, indicating steady intensity across that interval.
Open the tropical storm tracks layer in RainViewer to follow Karina’s recorded centre positions. Each track point shows the storm’s category at that moment: tropical depression points are cyan, tropical storm points are blue, category 1 points are yellow, category 2 points are amber, category 3 points are orange, category 4 points are red, and category 5 points are dark red. The track shows Karina’s progression from depression to category 4 hurricane over open eastern Pacific water.
Compare the latest point with earlier points to see Karina’s westward and west-northwestward movement, changes in forward speed and changes in intensity. RainViewer displays the recorded path, while official warnings and current public safety information come from the national weather service.

Karina’s strongest recorded intensity is category 4, with sustained wind of 232 km/h, gusts of 267 km/h and pressure of 940 mb. The storm reaches these values in the September 2 readings.
Karina is a tropical storm at 00:00 UTC on August 30 and reaches category 1 hurricane strength six hours later. Karina reaches category 3 strength another 18 hours after that and category 4 strength six hours later.
The coordinates identify Karina’s centre, while the wind and pressure values describe the storm at that reading. The movement value gives direction in degrees and forward speed in kilometres per hour; it does not describe weather at any nearby place.
Tropical cyclones receive names from predetermined naming lists used for their basin. Names make it easier to distinguish one storm from another in weather information and historical records.
