Since 1950, only one storm has had stronger winds in the Atlantic than Dorian has right now.
Hurricane Allen in 1980 had maximum winds of 190 mph.
Here's a look at the strongest storms the Atlantic has seen:

Hurricane Dorian made landfall moments ago on the Abaco Islands in the Bahamas. The storm is a dangerous Category 5 and is continuing to churn northwestward.
The storm has sustained winds of 185 mph. Gusts over 200 mph are being experienced there while storm surge up to and over 20 feet is likely occurring. Extreme rainfall rates will likely lead to flash flooding.
Here's what else to expect each day this week:
Tropical storm-force winds will begin to move into the Florida Peninsula on Monday morning, likely occurring first in the West Palm Beach/Port St. Lucie area.
Dorian is slowly moving northwest and spreading tropical storm-force winds over more of Florida. By 8 p.m. ET Monday, tropical-storm force winds will be pushing into Central Florida.
By Tuesday, Hurricane Dorian should have weakened to a Category 4, with winds around 140 mph near the center. Tuesday will see Dorian start to make its closest pass to Florida as it turns to the north and parallels the coastline. Again, though the official forecast calls for the center of the storm to stay around 40-50 miles off shore, any slight deviation could bring the eye into Florida. Even if it doesn’t, hurricane force winds are likely to be over land on Tuesday along Florida’s east coast. Rain should be steady but might not be constant, depending on how close the storm gets.
At 8 a.m., the center of Dorian should be within about 50 miles of Port St Lucie/Vero Beach area. It will move northward during the day and evening.
The storm will continue to produce hurricane-force winds as it heads north with some more weakening forecast. There is an increasing risk of strong winds and dangerous storm surge along the coasts of Georgia, South Carolina and North Carolina.
This will be the closest approach to the Carolina coast. There is also the possibility of a landfall.
The storm will near the outer banks of North Carolina.

The British Royal Navy auxiliary aid ship, RFA Mounts Bay, has been deployed to offer support during Hurricane Dorian, according to the Ministry of Defense press office.
The ship is ready to assist if help is needed in the Bahamas. It is fully equipped, capable of carrying amphibious vehicle and includes a helicopter for rescue and surveying operations, a statement from the department said.
The Royal Navy deploys ships every year ahead of hurricane season across different overseas territories — including the commonwealth areas — as part of their standard protocol to provide humanitarian and disaster relief.
The ship’s current position is not known, but its last whereabouts were near the British Virgin Islands roughly two days ago, the department said.
Mandatory evacuations have been ordered for North and South Hutchinson Island, St Lucie County Sheriff Ken Mascara said at an afternoon news briefing.
Manufactured homes and low-laying areas are also under a mandatory evacuation. Effective tomorrow, access to the area will be limited to residents and businesses only, Mascara said.
“This storm is very unpredictable,” said Mascara, who advised residents to get to shelters. “Our concern has grown, and so should yours."
Authorities warn against anyone who tries to take advantage of homes or businesses that are vulnerable. Last night someone attempted to “burglarize a house that was vacated,” Mascara said.
“We are watching for this kind of activity,” Mascara added.
Hurricane Dorian made landfall on Elbow Cay in the Bahamas' Abacos Islands at 12:40 p.m. ET, according to the National Hurricane Center.
The storm is a Category 5 hurricane with 185 mph winds.
"This is a life-threatening situation. Residents there should take immediate shelter. Do not venture into the eye if it passes over your location," the center said in an advisory.sonos sonos One (Gen 2) - Voice Controlled Smart Speaker with Amazon Alexa Built-in - Black read more

Dorian, which is crawling over the Northern Bahamas, is forecast to travel about 120 miles in the 36 hours between Sunday and Tuesday.
That means the hurricane is averaging about 3 mph — a walking pace.
Dorian has winds of 180 mph, making it the strongest hurricane in modern records for the Northern Bahamas.

President Trump called Hurricane Dorian “one of the biggest hurricanes we’ve ever seen” as he spoke with reporters after returning from Camp David.
The President said he has been tracking the storm and doing “a lot of different things, going over the hurricane.”
"This is now a Category 5,” Trump said. “It seems to be one of the biggest hurricanes we’ve ever seen, and that’s a problem.”
"We have a lot of great people working right now. We don’t know where it’s going to hit but we have an idea," Trump added.
Trump was accompanied into the White House by Rear Admiral Peter Brown of the US Coast Guard, who warned of “substantial, destructive, life-threatening storm surge” associated with the storm.
"We’ll be learning over the next probably less than 24 hours,” Trump said.
The President will head to FEMA headquarters in Washington Sunday afternoon to receive a briefing on the hurricane. He told reporters that he’ll be holding a press conference after his meetings.
Parts of the Atlantic coast of Florida are now under a storm surge watch, according to the National Hurricane Center.
The watch runs from North of Deerfield Beach to the Volusia/Brevard County Line, the center said.
What you need to know: A storm surge watch means there is a possibility of life-threatening inundation from rising water moving inland from the coastline in the indicated locations over the next 48 hours.
Here's a look at the area on the map:
Parts of Florida are now under mandatory and voluntary evacuation as Hurricane Dorian nears the state. Here's a breakdown:
Brevard County are now calling for evacuations to begin at 8 a.m. ET Monday. The following residents should start evacuating then:
The mandatory evacuation was initially to begin at 8 a.m. Sunday. However, the path of the slow-moving Dorian has allowed more time for residents to prepare for a major water and wind event still threatening Brevard County beginning on Tuesday.
Palm Beach County
The eastern half of Palm Beach County is now under a tropical storm warning due to the approach of Hurricane Dorian. Due to this, mandatory evacuations are being ordered for residential structures in Zone A and Zone B in Palm Beach County, effective at 1 p.m. ET today.
