Part of the 1997 Pacific hurricane season

Hurricane Linda was an extremely powerful

rapidly intensified, reaching sustained winds of 185 mph (295 km/h) and an estimated central pressure of 902 millibars (26.6 inHg); both were records for the eastern Pacific until Hurricane Patricia surpassed them in 2015. The hurricane was briefly forecast to move toward southern California, but instead, it turned out to sea and lost its status as a tropical cyclone on September 17, before dissipating on September 21. Linda was the fifteenth tropical cyclone, thirteenth named storm, seventh hurricane, and fifth major hurricane of the 1997 Pacific hurricane season. Linda was also the most intense tropical cyclone worldwide in 1997
.

While near peak intensity, Hurricane Linda passed near

landfall on southern California as predicted, it would have been the strongest storm to do so since a storm in 1939. Though it did not hit the state, the hurricane produced light to moderate rainfall across the region, causing mudslides and flooding in the San Gorgonio Wilderness
; two houses were destroyed and 77 others were damaged, and damage totaled US$3.2 million.

The origins of Hurricane Linda are believed to have been in a

convection developed to the west of Panama in the Pacific Ocean on September 6, which is believed to have been related to the tropical wave. The system continued westward, and within three days of entering the basin, a poorly defined circulation formed. Banding features began to develop, and at around 1200 UTC on September 9, the system organized into Tropical Depression Fourteen-E. At the time, it was approximately 460 miles (740 km) south of the Mexican city of Manzanillo.[1]

On becoming a tropical cyclone, the depression moved northwestward at 6 and 12 miles per hour (9.7 and 19.3 km/h), partially under the influence of a

Saffir-Simpson scale, and around 0600 UTC, Linda attained estimated peak winds of 185 mph (298 km/h) about 145 mi (233 km) southeast of Socorro Island.[1] Its maximum sustained winds were estimated between 180 and 195 mph (290 and 314 km/h), based on Dvorak T-numbers of 7.5 and 8.0 respectively,[1] and gusts were estimated to have reached 220 mph (350 km/h).[3] The hurricane's pressure is estimated at 902 millibars (26.6 inHg), making Linda the most intense Pacific hurricane at the time.[1] When the storm was active, its pressure was estimated to have been slightly lower, at 900 millibars (27 inHg).[4]

Shortly after reaching peak intensity, Hurricane Linda passed near Socorro Island as a Category 5 hurricane.

Hurricane Hunters and airplanes from National Oceanic and Atmospheric Administration investigated the hurricane to provide better data on the powerful hurricane.[5] Hurricane Linda quickly deteriorated as it tracked toward cooler waters, weakening to tropical storm status on September 15. Two days later, when located about 1,105 miles (1,778 km) west of the southern tip of the Baja California peninsula, it weakened to tropical depression status. Linda no longer met the criteria for a tropical cyclone by September 18, although its remnant circulation persisted for a few more days before dissipating.[1]

Forecasters and computer models did not anticipate how quickly Linda would strengthen; in one advisory, the NHC under-forecast how strong the winds would be in 72 hours by 115 miles per hour (185 km/h).[7] The maximum potential intensity for Linda was 880 millibars (26 inHg), 22 millibars (0.65 inHg) lower than its actual intensity.[8] The 1997 season was affected by the 1997–98 El Niño event, which brought warmer than normal water temperatures and contributed to the high intensity of several storms. Hurricane Linda occurred about a month after the similarly powerful Hurricane Guillermo, which also reached Category 5 status. The passage of Linda cooled the waters in the region, causing Hurricane Nora to weaken when it passed through the area on September 21.[5]

Forecast track of Linda on September 13, showing a track towards Southern California

When Linda was predicted to turn towards the northeast, it was forecast to move ashore in Southern California as a weak tropical storm, which would have made Linda the first to do so since a tropical storm in 1939.[3][10] The Oxnard, California National Weather Service office issued public information and special weather statements that discussed the possible impact of Linda on southern California. The advisories mentioned forecasting uncertainty, and advised the media not to exaggerate the storm.[1] The office noted a threat for significant rainfall—possibly causing flash flooding—as well as high surf.[4] To prepare for possible flooding, workers cleaned storm drains and prepared sandbags for coastal properties.[11]

Although the storm did not make the turn, 15 and 18 feet (4.6 and 5.5 m) waves reached southern California.

USD).[3] San Diego recorded 0.05 inches (1.3 mm) of rain, the first measurable precipitation in 164 days; this tied the record for the longest duration without rainfall at the station, previously set in 1915 and 1924. Long Beach had a dry spell for 215 days, rain since February 12 to September 14, 1997. Moisture from Linda extended into the Upper Midwest, contributing to a record daily rainfall total of 1.97 inches (50 mm) in Minneapolis, Minnesota.[13]

Records

With an estimated minimum central pressure of 902 millibars (26.6 inHg), Hurricane Linda became the most intense Pacific hurricane since reliable records began in

Hurricane Ava in 1973, which had a confirmed minimum pressure of 915 millibars (27.0 inHg). Since no observations recorded the pressure during Linda's peak, its peak intensity was estimated. As such, Ava remained the strongest directly measured hurricane in the basin at the time.[1][14][15]
