Hurricane Michael is currently a weakening tropical cyclone that is over Georgia. With a minimum central pressure of 919 mbar (hPa; 27.14 inHg), Michael was the third-most intense hurricane to make landfall on the United States, behind the 1935 Labor Day hurricane and Camille in 1969,[1] as well as the sixth-strongest landfalling hurricane in the United States by wind speed.

The thirteenth named storm, seventh hurricane, and second major hurricane of the 2018 Atlantic hurricane season, Michael originated from a broad low-pressure area in the western Caribbean Sea that became a tropical depression on October 7, after nearly a week of slow development. By the next day, Michael had intensified into a hurricane near the western tip of Cuba as it moved northward. Strengthening continued in the Gulf of Mexico, first to a major hurricane on October 9, and further to a Category 4 hurricane on the Saffir–Simpson scale. Approaching the Florida Panhandle, Michael attained peak winds of 155 mph (250 km/h) as it made landfall near Mexico Beach on October 10, becoming the first to do so in the region as a Category 4 hurricane. As it moved inland, the storm weakened and began to take a northeastward trajectory toward Chesapeake Bay.

By October 10, at least fourteen deaths had been attributed to Michael and its precursor, including 13 in Central America and 1 in the United States. In Cuba, the hurricane's winds left over 200,000 people without power.

Early on October 2, the NHC began monitoring a broad area of low pressure that had developed over the southwestern Caribbean Sea.[2] While strong upper-level winds initially inhibited development, the disturbance gradually became better organized as it drifted generally northward and then eastward toward the Yucatán Peninsula. By October 6, the disturbance had developed well-organized deep convection, although it still lacked a well-defined circulation. The storm was also posing an immediate land threat to the Yucatán Peninsula and Cuba. Thus, the NHC initiated advisories on Potential Tropical Cyclone Fourteen at 21:00 UTC that day.[3][4] By the morning of October 7, radar data from Belize found a closed center of circulation, while satellite estimates indicated a sufficiently organized convective pattern to classify the system as a tropical depression.[5] The newly-formed tropical cyclone then quickly strengthened into Tropical Storm Michael at 16:55 UTC that day.[6]

The nascent system meandered before the center relocated closer to the center of deep convection, as reported by reconnaissance aircraft that was investigating the storm.[7] Despite moderate vertical wind shear, Michael proceeded to strengthen quickly, becoming a high-end tropical storm early on October 8, as the storm's cloud pattern became better organized.[8] Continued intensification occurred, and Michael attained hurricane status later on the same day.[9] Rapid intensification began to ensue as very deep bursts of convection were noted within the eyewall of the growing hurricane, as it passed through the Yucatán Channel into the Gulf of Mexico late on October 8, clipping the western end of Cuba, while a 35 nmi (65 km) wide eye was noted to be forming.[10] The intensification process accelerated on October 9, with Michael becoming a major hurricane at 21:00 UTC that day.[11] In addition, the central pressure in the eye was noted to have dropped about 20 mb (0.59 inHg) in the span of 6 hours into the first hours of October 10.[12] Rapid intensification continued throughout the day as a well-defined eye appeared, culminating with Michael achieving its peak intensity at 18:00 UTC that day as a high-end Category 4 hurricane, with maximum sustained winds of 155 mph (250 km/h) and a minimum central pressure of 919 mbar (27.14 inHg), as it made landfall near Mexico Beach, Florida, ranking by pressure as the third-most intense Atlantic hurricane to ever make landfall in the United States.[13] Michael is the most intense recorded hurricane to have struck land during the month of October in the North Atlantic basin (including the Gulf of Mexico and the Caribbean Sea),[14] and is one of two Category 4 hurricanes to have hit Florida in October, the other being Hurricane King in 1950.[15] Michael is also the first recorded Category 4 hurricane in the Florida Panhandle since 1851.[16] After landfall, Michael gradually weakened, dropping to Category 3 intensity at 21:00 UTC, and then to Category 1 intensity by 00:00 UTC on the next day (8:00 PM EDT on October 10).

As of 1:00 p.m. CDT (18:00 UTC) October 10, Hurricane Michael is located within 15 nautical miles of 30°00′N 85°30′W / 30.0°N 85.5°W / 30.0; -85.5 (Michael), about 5 miles (10 km) northwest of Mexico Beach, Florida and about 20 miles (30 km) southeast of Panama City, Florida. Maximum sustained winds are 135 knots (155 mph, 250 km/h), with gusts to 155 knots (180 mph, 285 km/h). The minimum barometric pressure is 919 mbar (hPa; 27.41 inHg), and the system is moving north-northeast at 12 knots (14 mph, 22 km/h). Hurricane-force winds extend up to 45 miles (75 km) from the center of Michael, and tropical storm-force winds up to 175 miles (280 km) from the center.

Preparations and impact

Central America

The combined effects of the precursor low to Michael and a disturbance over the Pacific Ocean caused significant flooding across Central America.[19] At least thirteen fatalities occurred: six in Honduras,[20] four in Nicaragua, and three in El Salvador. Nearly 2,000 homes in Nicaragua suffered damage, and 1,115 people were evacuated. A total of 253 homes were damaged in El Salvador, and 180 in Honduras.[19] More than 22,700 people were directly affected throughout the three countries.[20]

Cuba

About 300 people evacuated in western Cuba due to the storm.[21] About 70% of the offshore Isla de la Juventud lost power.[22] High winds left 200,651 people without power in Pinar del Río Province.[21] Officials sent 500 power workers to the area to restore electricity.[21]

On October 7, Florida Governor Rick Scott announced that he would be declaring a state of emergency for Florida if needed, advising residents to be prepared for the incoming storm.[23] That day, a state of emergency was declared for 26 counties, and then 9 additional counties were added on October 8. Governor Scott also requested that President Donald Trump issue an emergency disaster declaration for 35 counties, with Trump approving of the request on October 9.[24] Officials in Bay, Gulf, and Wakulla counties issued mandatory evacuation orders on October 8 for those living near the coast, in mobile homes, or in other weak dwellings.[25] Florida State University's main campus in Tallahassee and a satellite campus in Panama City is to be closed from October 9 through October 12, with classes and business expected to resume on October 15. Florida A&M University and Tallahassee Community College are closing several campuses through October 14, while weekend classes and events were canceled at the former.[26] Public schools were closed in 26 counties, mainly in the Florida Panhandle.[24] On October 8, Hurricane and Tropical Storm Warnings and Watches were issued for the Gulf Coast.

Georgia Governor Nathan Deal declared a state of emergency for 92 counties in the southern and central portions of the state on October 9. Several colleges and universities in south Georgia are to close for a few days.[27]

375,000 people have been asked to evacuate as the storm strengthens, with sustained winds of 150 mph and storm surge up to 13 feet expected.[28]

Landfall

The storm made landfall as a high-end Category 4 hurricane, with maximum sustained winds of 155 mph, at 12:15 CST (13:15 EST) on October 10, in Mexico Beach and near Tyndall Air Force Base.[29][30][1] On October 10, 2018, Florida Governor Rick Scott stated that Michael was the "worst storm that [the] Florida Panhandle has seen in a century."[31] One death occurred in Greensboro after a tree fell on a house.[32]

Records

With top sustained winds of 155 mph (250 km/h) and a central pressure of 919 mbar (hPa; 27.14 inHg) at landfall, Michael is the most intense landfalling U.S. hurricane since Camille in 1969, which had a central pressure of 900 mbar (hPa; 26.58 inHg), and the strongest by wind speed since Andrew in 1992, which had 165 mph (270 km/h) winds.[1] Along with 2017's Hurricane Maria and a typhoon in 1900, Michael is tied for the sixth-strongest tropical cyclone by wind to impact the United States, and is the fourth strongest to impact the U.S. mainland.[33]

As it moved inland into southwestern Georgia, Michael weakened to a Category 3 hurricane with winds of 115 mph (185 km/h),[34] becoming the first major hurricane to impact the state since 1898.[35]
