Hurricane Franklin

Hurricane Franklin
Category 1 hurricane (SSHWS/NWS)

Hurricane Franklin near peak intensity shortly before landfall in Mexico late on August 9
Formed August 7, 2017
Dissipated August 10, 2017
Highest winds 1-minute sustained: 85 mph (140 km/h)
Lowest pressure 981 mbar (hPa); 28.97 inHg
Damage Unknown
Areas affected Belize, Mexico (Yucatán Peninsula, Veracruz), Texas
Part of the 2017 Atlantic hurricane season

Hurricane Franklin was the first hurricane to make landfall in the Mexican state of Veracruz since Hurricane Karl in 2010. The sixth named storm and first hurricane of the 2017 Atlantic hurricane season, Franklin formed on August 7 out of a tropical wave that was first tracked in the southeastern Caribbean Sea on August 3. The storm strengthened within a favorable environment and made landfall on the Yucatán Peninsula as a moderate tropical storm early on August 8 north of Belize. Weakening occurred as it crossed the peninsula, but Franklin re-emerged into the Bay of Campeche later that day, restrengthening quickly to become the season's first hurricane. It made landfall near Lechuguillas, Veracruz, on August 10 as a Category 1 hurricane, before rapidly weakening over the mountainous terrain of Mexico and dissipating shortly afterwards. On August 12, the storm's remnants combined with a developing low in the Eastern Pacific to form Tropical Storm Jova.

Meteorological history

On August 3, the National Hurricane Center (NHC) began monitoring a tropical wave that was located in the southeastern Caribbean Sea for possible tropical cyclogenesis.[1] Relatively little change in organization occurred over the next two to three days as it moved westward at 10–15 mph (16–24 km/h), although global models continued to indicate that it could develop further once it got to the Bay of Campeche. Early on August 5, convection associated with the wave increased, signaling organization.[2] Continued improvement of the wave led to development of a broad area of low pressure on August 6 roughly 150 miles (240 km) east of Honduras,[3] which led to the designation of Potential Tropical Cyclone Seven at 21:00 UTC that day.[4] A buoy over the western Caribbean near the disturbance reported sustained gale-force winds, and combined with satellite images indicating that the circulation had become better defined, indicated that the disturbance became Tropical Storm Franklin at 03:00 UTC on August 7.[5]

Located in a relatively favorable environment, with the only inhibiting factor being proximity to land, Franklin strengthened to an initial peak intensity of 60 mph (95 km/h) on August 7 before moving ashore near Pulticub, Quintana Roo, at 03:00 UTC on August 8.[6] The cyclone weakened considerably while over the peninsula, however the satellite presentation remained well-defined, and the inner core tightened up considerably.[7] Later that day, Franklin emerged into the Bay of Campeche and immediately began strengthening again, becoming a hurricane at 21:00 UTC on August 9.[8] It achieved its peak intensity at 00:00 UTC on August 10 with winds of 85 mph (140 km/h) and a pressure of 981 mbar (29.0 inHg),[9] shortly before making landfall in Lechuguillas, Mexico five hours later.[10] This made it the first hurricane to strike the Veracruz region since Karl in 2010.[11] The cyclone rapidly weakened over the mountainous terrain of Mexico and dissipated shortly afterwards.[12] The mid-level circulation of Franklin, however, remained intact as it traversed the mountainous terrain, and the remnants eventually regenerated into Tropical Storm Jova in the Eastern Pacific early on August 12.[13]

Immediately upon classification of Franklin as a potential tropical cyclone, tropical storm warnings were issued for much of the eastern side of the Yucatán Peninsula on August 6;[4] a small portion of the coastline was issued a hurricane watch with the possibility of Franklin nearing hurricane intensity as it approached the coastline the next night. Approximately 330 people were reported to have gone into storm shelters, and around 2,200 relocated from the islands near the coastline to farther inland in advance of the storm.[14] In Belize, damage was reported to be minimal as the storm tracked slightly more northwards than expected, lessening impacts.[14] However, some areas still received up to a foot of rain.[15]

Eastern Mexico

As Franklin approached the state of Veracruz, schools were shut down.[16] Throughout the state, many trees were downed, isolated power outages were reported, and homes were damaged. Banana plantations, an invaluable source of income for local residents, were also impacted and some reported total losses. Some rivers were flooded, roads were cut off, and a few landslides were reported.[16] A total of 1,562 people evacuated their homes in Huauchinango, located in the state of Puebla. Shelters were prepared while sailors and soldiers performed evacuations throughout mountainous regions as a precautionary measure.[17]

United States

Although rains from the outer bands of Franklin did not impact the United States, swells and rip currents were experienced across part of the coast of South Texas.[18] The National Weather Service in Brownsville, Texas, issued a high surf advisory through the night of August 10.[19]
