Hurricane Doreen was considered the worst tropical cyclone to affect California in 32 years. The tenth tropical cyclone, fourth named storm, and second hurricane of the otherwise inactive 1977 Pacific hurricane season, it developed on August 13. The depression tracked northwestward, intensifying into Tropical Storm Doreen later that day. Further strengthening occurred over the subsequent days, and Doreen attained its peak as a minimal hurricane early on August 15. Executing a turn towards the north-northwest, Doreen made its first landfall as a Category 1 hurricane on the Saffir–Simpson Hurricane Wind Scale near Puerto San Carlos. Drifting offshore, Doreen made a second and final landfall near the northern portion of the Baja California as a tropical storm before rapidly weakening to a tropical depression. The tropical depression dissipated south of southern California on August 18.

Hurricane Doreen and its remnants caused severe flooding in northwestern Mexico and the southwestern United States. In Mexico, heavy rainfall was reported on both Baja California and the mainland of Mexico. Flooding left 2,000 people homeless in Mexicali along the United States-Mexico border, in addition, 325 homes and businesses were destroyed in southern California. Several highways were also flooded during the passage of the storm, most notably, lanes on Interstate 8 and Interstate 15 were washed out. In San Diego and Imperial County, the total damage to agricultural interests was $25 million (1977 USD). In addition, eight fatalities were reported in California. Elsewhere, impact from Doreen was relatively light.

Meteorological history

Шаблон:Storm path The origins of Hurricane Doreen were a tropical disturbance which formed Шаблон:Convert west of Acapulco, on August 11. Over the next two days, the system drifted westward at Шаблон:Convert. By 0000 UTC August 13, the Eastern Pacific Hurricane Center began classifying the system as Tropical Depression Ten, centered Шаблон:Convert west of Acapulco, Mexico. Immediately after developing, the depression curved northwestward, and began slowly intensifying over sea surface temperatures (SST's) of Шаблон:Convert. By 1800 UTC, winds increased to 50 mph (85 km/h), and the depression was then upgraded to Tropical Storm Doreen, which was centered about Шаблон:Convert west-northwest of Acapulco. Air Force reconnaissance began investigating Doreen late on August 14, and located the center about Шаблон:Convert south of the tip of Baja California. Another flight into the storm shortly thereafter confirmed that Doreen had intensified into a hurricane at 1800 UTC.[1]

At that time, the eye of Doreen was around Шаблон:Convert in diameter. After becoming a hurricane, Doreen re-curved to the north-northwest as it sped up slightly to Шаблон:Convert. Doreen approached the Baja California Peninsula, as it maintained minimal hurricane status. By August 18 at 1800 UTC, Doreen was centered only Шаблон:Convert when it curved northwestward. Late on August 18, the storm made landfall on the western coast of Baja California as a minimal hurricane. Unlike Hurricane Kathleen in 1976 which accelerated inland, Doreen moved slowly and re-emerged into the Pacific Ocean, over SST's of less than Шаблон:Convert. As a result, Doreen weakened to a tropical storm before making another landfall on the Port Eugenia Peninsula on August 16 shortly after 0600 UTC. Once again, Doreen quickly re-emerged into the Pacific Ocean over the Bay of Sebastián Vizcaíno. Due to SST's as low as Шаблон:Convert, Doreen continued to weaken, and was downgraded to a tropical depression early on August 17. After satellite imagery noted a poorly-defined low-level circulation, the final advisory was issued on Doreen, which was centered about Шаблон:Convert west of San Clemente Island, California at 0000 UTC on August 18. The remnants of the storm tracked into the Southwestern United States and dissipated over the Colorado River Valley.[1]

Rainfall summary for Hurricane Doreen

Hurricane Doreen dropped heavy rainfall along the western portions of Mexico and the Southwestern Region of the United States. In Mexico, Doreen produced heaviest precipitation along the Baja California peninsula, where rainfall peaked at Шаблон:Convert in the Los Cabos Area. The mainland of Mexico also received heavy rainfall, especially in the Sierra Madre Oriental mountains.[2] In the city of Mexicali, the storm left more than 2,000 people homeless, many of which lived in shanty-style homes.[3]

California

In anticipation of the storm, flash flood warnings were issued in the Colorado River Valley area, and were extended into southern California on August 16,[1] including places such as Santa Barbara County, the mountains of San Diego County, Riverside County, and portions of the Mohave Desert.[3][4] Heavy rainfall fell in southern California on August 16. An average of Шаблон:Convert of rain fell over low-lying areas of southern California for a period of three days. Heavier precipitation was reported in the mountainous areas, where rainfall peaked at Шаблон:Convert on San Jacinto Peak. Several other locations also reported heavy rainfall; Шаблон:Convert was reported in Calexico and Шаблон:Convert fell at Mitchell Caverns.[1][2] At Edwards Air Force Base, the launch of Space Shuttle Enterprise on August 31 was delayed to September 7 after rainfall from Doreen flooded the runway of the previous flight.[5]

In addition to heavy rain, high winds were reported. In Palm Springs, wind gusts were reported as high as 60 mph (95 km/h). As a result, several trees were felled and power outages occurred. Highway 86 and 111 were under water from Brawley, near the Mexican border to the Salton Sea. California State Route 98 was also flooded from Brawley to Blythe. Two of the four lanes on Interstate 15 were washed out from Los Angeles to Las Vegas, stranding thousands of gamblers in places like Barstow.[1][4] Ocotillo, a town that was devastated during Hurricane Kathleen in 1976, was flooded again. Buses were sent to evacuate the townspeople, but the residents declined to evacuate. Overall, damage totaled $25 million, mostly in agricultural losses in San Diego and Imperial Counties.[1] Eight deaths were reported. Six children were swept away in the Los Angeles River; five of them were rescued, but the sixth was later presumed dead.[3]

Arizona

Doreen also produced heavy rainfall in a small area of southwestern Arizona, limited to the Yuma area. Along the border of Arizona, California, and Mexico, rainfall was recorded between Шаблон:Convert.[6] Rainfall in the state of Arizona had peaked at Шаблон:Convert in that area.[7] Light to moderate rainfall also occurred in other areas of the state, such as Nogales, where Шаблон:Convert of precipitation was recorded.[6] Damage to roads, levees, houses, dikes were reported throughout the state, especially in the Bullhead City area.[8]

While surveying damage in southwestern Arizona, a request was made to then-Governor Raul Hector Castro for $750,000 in emergency services funds. The American Red Cross had been in the area and spent $12,000 to assist families that were left homeless after the flood.[8]

Elsewhere in the United States

Further west, larger swaths of rainfall occurred in Nevada, though precipitation was generally light with many areas experiencing less than Шаблон:Convert. Rainfall in Nevada had peaked at Шаблон:Convert in Avaden,[2] making Doreen the wettest tropical cyclone for the state of Nevada as of 2011.Шаблон:US States Tropical Cyclone Point Maxima In Las Vegas, major intersections were flooded due to Шаблон:Convert of rain. In addition to street flooding, some roofs of houses and buildings collapsed.[3]

In New Mexico, lesser amounts of rainfall were reported, and precipitation was limited to the northeastern and southwestern portions of the state. Much it the rainfall was between Шаблон:Convert,[2] and precipitation with the state peaked at Шаблон:Convert in the city of Florida.[7] Rainfall was also minimal in the state of Utah, with only a few isolated areas reporting light precipitation, and generally did not exceed Шаблон:Convert.[2] However, rainfall peaked at Шаблон:Convert in Logan.[7]
