Hurricane Diana was a deadly tropical cyclone which struck Mexico in August 1990. The fourth named storm and second hurricane of the season, Diana developed from a tropical wave in the southwestern Caribbean Sea on August 4. Forming as a tropical depression, the system brushed Honduras before intensifying into a tropical storm the following day. Continuing to gradually strengthen, Diana made its first landfall in Mexico's Yucatán Peninsula as a strong tropical storm late on August 5. The cyclone weakened slightly due to land interaction, before emerging into the Bay of Campeche on August 6. Once over water, warm sea surface temperatures allowed Diana to quickly become a hurricane and later peak as a Category 2 on the Saffir–Simpson Hurricane Scale on August 27. Shortly thereafter, the storm made landfall near Tampico, Tamaulipas, with winds of 100 mph (165 km/h). Rapid weakening ensued once the storm moved over the high terrain of Mexico, with Diana diminishing to a tropical depression roughly 24 hours after moving onshore. The cyclone later emerged into the Gulf of California on August 9 shortly before dissipating. The remnant disturbance was monitored until due it lost its identity over Arizona on August 14.

Diana left relatively minor impacts in the Yucatán Peninsula. Some locations observed tropical storm-force sustained winds and gusts, while heavy rains left street flooding in the Chetumal area. Along the Gulf Coast of Mexico, the hurricane produced torrential rains exceeding 20 in (510 mm) in some places. The ensuing floods left about 3,500 people homeless and destroyed roughly 155 mi² (400 km²) of farmland. Numerous roads and railways were either washed out or blocked by debris, cutting communication with several communities. In all, Diana killed 139 people in Mexico and resulted in approximately $90 million (1990 USD) in damage. The remnant disturbance caused street flooding in Arizona. The World Meteorological Organization retired the name Diana following the season due to the extensive loss of life and damage caused by the storm.

The origins of Hurricane Diana were from a tropical wave that existed western Africa into the Atlantic on July 27. Conditions were unfavorable for development of a tropical cyclone, and the tropical wave remained disorganized until reaching the eastern Caribbean Sea. The system entered the Caribbean Sea through the southern Windward Islands, where falling barometric pressures were observed, decreasing by 3.5 mbar (hPa; 0.1 inHg) in 24 hours. Upper-level air data from the Lesser Antilles indicated that the tropical wave was associated with an upper-level anticyclone. With increasing convection, the first Air Force reconnaissance plane flight indicated no low-level circulation, but a relatively large amount of thunderstorm activity. The system continued to have a large amount of associated convection while passing over the Netherlands Antilles, as indicated by satellite images and surface observations. Cyclonic rotation was observed in the low-level convection by satellite images, and the fifth tropical depression of the season had developed at 0000 UTC on August 4, situated in the southwestern Caribbean Sea. However, this was based on surface observations, and it was not confirmed that tropical cyclone formation occurred until later that day.[1]

The new tropical depression moved to the northwest under the influence of a mid-level trough, and rapidly intensified to a tropical storm the following day offshore of eastern Honduras; the National Hurricane Center assigned the name Diana to the system. Becoming a tropical storm, Diana further intensified, and winds reached 65 mph (105 km/h) before landfall in Felipe Carrillo Puerto in Quintana Roo occurred. The storm initially rapidly weakened over land, although it retained winds of 50 mph (80 km/h) until moving over open waters. When Diana entered the southern Gulf of Mexico, the trough of low pressure in that vicinity weakened and steering currents caused the storm to head westward. Conditions became more favorable in the Gulf of Mexico, and Diana quickly intensified, becoming a hurricane late on August 7. Hurricane Diana rapidly intensified, and briefly reached Category 2 hurricane status, attaining peak intensity with winds of 100 mph (165 km/h) and a minimum barometric pressure of 980 mbar (hPa; 28.94 inHg). Only two hours after attaining peak intensity on August 7, Hurricane Diana made landfall near Tampico, Tamaulipas at the same intensity.[1]

Moving inland, Diana rapidly weakened over the high terrain of Mexico, quickly deteriorating from a low-end Category 2 hurricane to a strong tropical storm within four hours. Diana continued westward over Mexico, and weakened to a tropical depression on August 8, while centered near Mexico City. The weakening tropical depression turned west-northwestward over central Mexico, and emerged into the Pacific Ocean on August 9, before dissipating in the Gulf of California.[1] The remnants of Hurricane Diana curved northward and tracked through the Gulf of California, and eventually came ashore in northwestern Sonora. Crossing northwestern Mexico, the remnants of Diana entered Arizona and quickly dissipated.[2]

Preparations

In anticipation of Diana's first landfall, a tropical storm warning was issued on August 5 for Cancún, Mexico, southward to Belize City, Belize, on August 5, including the offshore islands from both nations; a tropical storm warning indicates that tropical storm force winds, 39 to 73 mph (39 to 118 km/h), are expected within 24 hours. Eleven hours later, the tropical storm warning was extended as far as Carmen, but was discontinued for the entire east coast of Belize.[3] Residents along coastal areas of Quintana Roo were advised to evacuate inland,[4] as tides were expected to range from 3 to 5 ft (0.91 to 1.52 m) above normal.[5] Emergency officials set up shelters were set up in Xcalak, Punta Herrero, and Punta Allen.[4] The Mexican Coast Guard was placed on alert and shipping across Quantana Roo was suspended during the evening of August 5. Additionally, there were concerns about flash flooding due to the possibility of 5 to 8 in (130 to 200 mm) of rainfall in areas near the storm's path.[5] After Diana made landfall on the Yucatán Peninsula on August 6, all of the tropical storm warnings in place were discontinued.[3]

Diana then threatened the mainland east coast of Mexico. A hurricane watch was issued for Tuxpan to Boca de Jesus Maria at 21:00 UTC on August 6; a hurricane watch notes the possibility of hurricane conditions within 48 hours, such as winds of at least 74 mph (119 km/h). Early on August 7, the National Hurricane Center anticipated hurricane conditions within 24 hours, and as a result, a hurricane warning was issued for Nautla to Le Pesca. Simultaneously, a tropical storm warning was issued for La Pesca to Boca de Jesus Maria. Later that day, a hurricane warning had been issued for a similar area, stretching from Nautla to Lerdo de Tejada.[3] The National Hurricane Center also predicted precipitation totals of 8 in (200 mm) and emphasized that flash floods and mudslides would likely occurred in the vicinity of where Diana was projected to make landfall.[6] According to Miguelangel Rebolledo, the captain of the port of Tuxpan, about 300 people fled low-lying areas.[7] State and federal officials prepared 10,000 packages of emergency supplies, food, and medicine and moved them to several locations along the coast. Police and Armed Forces were placed on alert.[8] By 00:00 UTC on August 8, all of the watches and warnings in place were officially discontinued.[3]

Rainfall from Diana in Mexico

Mexico

Offshore Quintana Roo, the island Cozumel of reported sustained winds of 45 mph (75 km/h).[9] While crossing over the Yucatán Peninsula, sustained winds of 34 mph (54 km/h) and gusts to 40 mph (65 km/h) were observed in Mérida. In addition, wind gusts of 37 and 45 mph (60 and 73 km/h) were reported in the towns of Felipe Carrillo Puerto and José María Morelos, respectively.[10] Diana also caused heavy rain across the area, though damage is unknown.[11] Due to heavy rainfall, minor street flooding occurred in Chetumal, Quintana Roo.[12]

Along the Gulf of Mexico, the storm produced storm surge and abnormally high tides, with waves up to 12 ft (3.6 m) in height.[13] Rough seas resulted in the closures of the ports at Coatzacoalcos and Tampico.[14] Diana produced torrential rainfall while crossing the country, which peaked at 21.92 in (557 mm) in Aquismón, San Luis Potosí.[2] Heavy rainfall triggered mudslides and flooding, mostly in the east-central portion of Mexico. The Comisión Nacional del Agua noted that at least seven rivers in the lower Pánuco River basin threatened to overflow their banks in the states of Guanajuato, Jalisco, San Luis Potosí, and Tamaulipas.[15] The rainfall caused extensive property damage, destroying numerous houses and leaving 3,500 homeless.[16] Flooding inundated highways and railways across six states and destroyed about 155 mi² (400 km²) of farmland.[14]

On mainland Mexico, the states of Veracruz, Hidalgo, and Puebla were hardest hit, with over 75,000 people affected by the hurricane.[14] In Poza Rica, high winds toppled trees and electricity poles, which cut off telephone services and electricity supply to the city. Fallen trees and telephone wires also blocked some streets in the area, but the major roads remained open.[7] Several miners were reported dead, after their truck plunged into a ravine.[17]

Excluding the 56 people still missing by the end of 1990, Diana caused at least 139 deaths and $90.7 million in damage.[14] However, some sources claim that there were as much as 391 fatalities and losses incurred by the storm totaled to $94.5 million.[18] In addition, it is estimated that Diana injured 25,000 people.[14] Following the storm, the Mexican Armed Forces delivered food and basic health care supplies. In addition, there was also a mass vaccination against typhoid.[19]

Elsewhere

While Diana was crossing the Yucatán Peninsula, it dropped light rainfall in Belize, peaking at 1 in (25 mm) in an unspecified location.[20] The remnants of Hurricane Diana eventually moved into the Southwestern United States, bringing heavy rainfall to the region.[2] In Imperial County, California, golf-ball sized hail was reported by the residents, along with rain and lightning, causing briefly power outages throughout the county. A police dispatch of Imperial County also noted local flooding, which resulted in traffic disruptions.[21] The remnants of Diana also dropped light rainfall in San Diego County, California, with the city of San Diego receiving only a trace of rain, Vista reporting 0.09 in (2 mm), Del Mar had 0.08 in (2 mm), and Oceanside measuring 0.3 in (8 mm).[22]

In Arizona, the remnants of Diana contributed to record cold temperatures for August in Phoenix. On August 14, the city had a high temperature of 78 °F (26 °C), which was 24 °F (−4 °C) below normal for that date. In Maricopa County, 3.5 in (89 mm) of rain was observed. Heavy precipitation, with 3.42 in (87 mm) in Desert Hills, which fell in less than two hours. Several weather-related car accidents occurred, but none were serious. In Apache Junction, police and city officials rushed to close flooded streets, including portions of state highways and underpasses of Interstate 17. Crews were pumping 32,000 US gal (120,000 L) of water from the underpasses of Interstate 17, but their efforts were futile. A 19 mi (31 km) portion of State Route 87 between Gila River Indian Community and the intersection with State Route 187 was shut down due to flooding. In Sacaton, about two-thirds of the city was inundated with at least 3 ft (0.91 m) of water.[23]

Due to its impact, the name Diana was retired by the World Meteorological Organization in the spring of 1991, and will never be used again for another Atlantic hurricane. It was replaced with Dolly for the 1996 season. This Hurricane Diana is not to be confused with the 1955 season's Hurricane Diane, which was also retired.[24]
