Hurricane Delta 'rapidly intensifies' to Category 4 storm, takes aim at Cancun before US Gulf Coast

Louisiana to the Florida Panhandle may be impacted by the storm

A rapidly strengthening Hurricane Delta is taking aim at the resort hotspot of Mexico's northeastern Yucatan Peninsula before targeting the U.S. Gulf Coast later this week.

The U.S. National Hurricane Center in Miami said Tuesday afternoon that Hurricane Delta is now a Category 4 storm, packing maximum sustained winds of 140 mph as it is located 260 miles east-southeast of Cozumel moving west-northwest at 16 mph. The storm was upped from a Category 3 to a 4 between 10:50 a.m. to 11:20 a.m. EDT, with forecasters labeling the storm as "dangerous."

"It's really intensified sitting over some very warm water," Fox News Meteorologist Adam Klotz said on "Outnumbered Overtime."

The storm rapidly intensified overnight from having 80 mph winds into a Category 4 hurricane with 140 mph gales and is expected to strengthen even further as it moves north into the Gulf of Mexico.

"Expected to bring a life-threatening storm surge and extreme winds," the NHC said Tuesday afternoon.

Delta is expected to stay a major hurricane -- Category 3 or higher --  by the time it reaches the Yucatan Peninsula on Wednesday and remain a powerful storm over the Gulf of Mexico through at least Thursday.

"Additional strengthening is forecast during the next 24 hours, and Delta is forecast to be an extremely dangerous Category 4 hurricane when it reaches the Yucatan peninsula Wednesday," the NHC said in its 11 a.m. EDT update. "Although some weakening is likely when Delta moves over the Yucatan peninsula, re-strengthening is forecast when the hurricane moves over the southern Gulf of Mexico."

Data from a U.S. Air Force Reserve Hurricane Hunter aircraft indicate that Delta will continue to strengthen as its forward speed increases, the NHC said. The storm is a small one, with hurricane-force winds extending outward only up to 25 miles from the center of the storm while tropical-storm-force winds reach up to 90 miles from the center.

Forecasters from the NHC noted that Delta is expected to reach a Category 4 storm while in the Gulf of Mexico as it moves over warm waters.

The brunt of the storm is expected to arrive along the northern Yucatan Peninsula starting Tuesday night, with a hurricane warning in effect for Tulum and Cozumel, resorts still being soaked by the remnants of Tropical Storm Gamma.

The NHC is warning of an extremely dangerous storm surge raising water levels by as much as 6 to 9 feet, accompanied by large and dangerous waves and flash flooding inland.

TROPICAL STORM DELTA STRENGTHENS IN CARIBBEAN, FORECAST TO TARGET GULF COAST AS HURRICANE

Delta “presents an important danger for the coastal regions” because of the storm surge in the lower parts of Quintana Roo, such as the resorts of Cancun, Holbox island or Isla Mujeres, Jorge Zavala, head of Mexico’s meteorological service, said in a press conference late Monday. The area is still feeling impacts from Tropical Storm Gamma.

Mexico began evacuating tourists and residents from coastal areas along its Riviera Maya Tuesday. Quintana Roo Gov. Carlos Joaquin said that buses were already carrying people off Holbox Island and all of the hotels in Puerto Morelos were busing their guests inland to government shelters.

Mexican President Andrés Manuel López Obrador said Tuesday that 5,000 federal troops and emergency personnel were being made available in Quintana Roo to aid in storm efforts.

Once Delta moves through Mexico, the storm is expected to curve in the Gulf of Mexico and take aim around Friday on the U.S. Gulf Coast.

Energy companies were also taking precautions on oil rigs, pulling nonessential workers from platforms on Monday in preparation for the storm's arrival.

Right now, it appears Louisiana will take the brunt of the worst of the impacts from this storm, but everyone along the coast needs to pay attention to the path of Delta.

"Expecting a Category 4 storm, that's not good news," Dean said Tuesday. " Really all of the Gulf Coast states need to monitor this."

As the storm gets closer to the U.S., the potential for heavy rain and flash flooding will extend from the Gulf Coast to the Tennessee River Valley and across the Southeast.

Dangerous rip currents are also impacting Gulf Coast beaches, according to the National Weather Service (NWS) forecast office in Mobile, Ala.

"We think Louisiana is in the crosshairs," Fox News Senior Meteorologist Janice Dean said on "Fox & Friends."

Louisiana Gov. John Bel Edwards urged residents to prepared, tweeting Tuesday the storm "will affect Louisiana and everyone needs to prepare accordingly."

In a news release on Monday, the governor said the State Emergency Operations Center (SEOC) has remained activated since March due to the ongoing COVID-19 fight and multiple tropical threats, including the ongoing recovery for Hurricane Laura.

“It’s unfortunate to have another system threaten Louisiana’s coastal parishes, but it is a situation we are prepared to handle," the governor said in a statement. "It is common for many people to experience hurricane fatigue during a busy season, but we need everyone to take this threat seriously."

If the storm makes landfall in the U.S., it would be the 10th storm to do so this season, which could break the record for storms to directly strike the continental U.S.

"I know we don't need to hear this, another hurricane, perhaps major hurricane making landfall once again this year which is going to be quite unfortunately dangerous for this area," Dean said Tuesday.

Delta is the 25th named storm in the 2020 Atlantic hurricane season, setting yet another record. The previous record for the earliest 25th Atlantic named storm is Nov. 15, 2005, according to Colorado State University hurricane research scientist Phil Klotzbach.

NOAA forecasters have called for up to 25 named storms this season with winds of 39 mph or higher; of those, seven to 10 could become hurricanes. Among those hurricanes, three to six will be major, classified as Category 3, 4 and 5 with winds of 111 mph or higher.

That's far above an average year. Based on 1981-to-2010 data, that is 12 named storms, six hurricanes and three major hurricanes.

So far this year, there have been 25 named storms, including eight hurricanes and of those, two major hurricanes. Delta is now the third major storm.

Laura caused major damage across southwestern Louisiana and southeastern Texas after roaring ashore as a Category 4 storm. Hurricane Sally made landfall last month in coastal Alabama, bringing damaging impacts along the Gulf Coast into Florida's Panhandle region.

The last time the Greek alphabet was used in the Atlantic was in 2005, the year of Hurricane Katrina. With a total of 27 storms that year, the first six letters of the Greek alphabet were used: Alpha, Beta, Gamma, Delta, Epsilon and Zeta.

With weeks to go until the season officially ends, the 2020 season could set the record for most named storms.
