Fernanda — 2023

Fernanda formed as a tropical depression on August 12 over the eastern Pacific near 14.2°N, 111.8°W, about 320 miles north-northwest of Clipperton Island. It moved generally west-northwest and then west, away from land. From August 12 to August 14, it rapidly strengthened from a 30-knot depression to a hurricane with 115-knot winds in 42 hours. It weakened quickly on August 16, became a remnant low on August 17, and dissipated on August 24. Fernanda made no landfalls and did not affect land. No coastal watches or warnings were issued. Its peak was on August 14 near 15.6°N, 118.0°W, about 510 miles west-southwest of Socorro Island, where it reached Category 4 strength, with maximum sustained winds of 115 knots (about 132 mph) and an estimated minimum pressure of 949 millibars. The report gives no storm-surge heights or rainfall totals. It also reports no damage or casualties associated with Fernanda, and no ship or land-based reports of tropical-storm-force winds. NHC track forecasts were more accurate than the five-year average at all forecast times evaluated. Intensity forecasts did not capture how strong Fernanda would become during its rapid strengthening, and many also missed its fast weakening on August 16.
