Six cyclones spin around the Southern Hemisphere simultaneously in rare meteorological event
Three formed in the Indian Ocean and another three formed in the Pacific, maps from Zoom Earth show. The tropical storms range from category one to category four level hurricanes, including Seru and Rae north of New Zealand, Alfred northeast of Australia, Bianca west of Australia, Honde off Mozambique and Garance off Madagascar.
Six simultaneous named storms last occurred in the Pacific Ocean in 1974, with five in the Atlantic in 1971.
Cyclone Alfred is set to make landfall in Australia on Thursday - click here for live updates.
It comes as meteorologists point to warm sea surface temperatures and weak wind shear as contributing factors to stronger storms in recent years. Both of these may be linked to La Nina weather phenomenon, AccuWeather Lead International Expert Jason Nicholls explained.
A marine heatwave near Western Australia has lasted since September 2024, with unusually high sea surface temperatures in late February.
The Australian Bureau of Meteorology predicted more severe tropical cyclones in the South Pacific this season as oceans were warmer than expected. The Southern Hemisphere's tropical season is from November to April.
Cyclone Rae
Category Level: 2
Cyclone Rae developed north of Fiji in the south-west Pacific on 22 February before travelling southwards.
It was a shorter-lived storm and was at maximum intensity when it reached category level two.
But it still caused significant damage to some of the Fiji islands on Monday, following heavy rain, flood waters, large waves and gusts of roughly 100mph.
Cyclone Seru
Category Level: 2
Cyclone Seru also developed in the south-west Pacific, forming on 24 February over the southern Soloman Islands.
It then travelled southwards, to the east of New Caledonia and Vanuatu.
Unlike Cyclone Rae, it remained offshore.
Cyclone Alfred
Category Level: 2
Cyclone Alfred originally developed in the Coral Sea in the Pacific on 24 February and it is expected to make landfall in Australia towards the end of this week.
The cyclone has barrelled towards Australia's southeastern coast, prompting evacuation orders and a state of emergency.
Officials have warned it could be one of the most destructive in the region in decades.
Cyclone Bianca
Category Level: 3
Cyclone Bianca formed in the Indian Ocean on 23 February. It developed offshore of Western Australia, moving to the west and southwest. It reached category three on 25 February but stayed far from land.
The Australian government announced it was not expected to impact mainland Australia and island communities.
Cyclone Honde
Category Level: 1
Cyclone Honde has caused devastation in Madagascar, with reports three people have died and 69 others injured.
More than 21,000 people have been forced to flee their homes in multiple cities, with widespread damage to homes and schools.
The storm formed in the Indian Ocean on 21 February alongside Bianca. It is expected to weaken and lose its tropical characteristics by Thursday.
Cyclones Garance
Category Level: 3
Cyclone Garance killed at least five people when it hit the French island of La Reunion on Friday.
It brought wind speeds of up to 96 mph - blowing away roofs, cutting off power and access to drinking water for many residents before exiting the southwest of the island hours later.
Dozens of tropical storms have hit the islands but the last cyclone to hit the island as a hurricane was in 1989.

Public beaches completely shut down along US coast days before end of summer with officers hunting down rulebreakers
PUBLIC beaches along the East Coast will be shut down for the next few days as dozens have already been rescued from rip currents. Rip currents are tearing through the East Coast's waves as Hurricane Erin approaches the US mainland. 3 3 3 Authorities reported that about 60 people have already needed to be rescued from beaches in the Carolinas, according to NBC affiliate WRAL, causing states in the northeast to shut their beaches frantically. "The force of the rip currents and rough surf along the Atlantic coast this week is life-threatening. Hurricane Erin is producing a tremendous amount of energy that will create hazardous beach conditions from Florida to New England," AccuWeather lead hurricane expert Alex DaSilva told USA Today. Storm advisories and swimming restrictions remain in effect in the Carolinas for the rest of the week. New York City Mayor Eric Adams warned all New Yorkers to steer clear of public beaches, as dangerous riptides threaten to occur with the arrival of Hurricane Erin. 'Swimming in the ocean will be prohibited over the next two days,' the mayor posted on X on Wednesday. 'NYC public beaches will be closed for swimming on Wednesday, August 20 and Thursday, August 21 due to high risk of rip currents from Hurricane Erin. 'Rip currents can sweep even strong swimmers out to sea quickly.' Iris Rodriguez-Rosa, the parks commissioner, also warned New Yorkers to avoid the beaches during the hurricane. 'We strongly urge all New Yorkers to heed these warnings and not risk their lives by entering the water,' Ms. Rodriguez-Rosa said in a statement. The National Weather Service posted on X about the high risk of life-threatening conditions for people who choose to visit the beach. Hurricane Erin weather fallout to hit Ireland in days as experts reveal wind and rain impact of horror weather event 'We are going to be a broken record this week. The ocean and specifically the surf zone will be dangerous this week,' the service posted. 'There is a HIGH Risk for Life Threatening Rip Currents. 'A High Surf Advisory is in effect for 5-8 waves Wednesday and 7-12 foot breaking waves Thursday.' Officials in New Jersey and Delaware are also urging Americans to avoid being near the coast at all costs as Hurricane Erin's winds could increase to 110 miles per hour. 'The impacts of Hurricane Erin will be felt across the Jersey Shore over the next several days, generating dangerous rip currents and high waves,' New Jersey Governor Phil Murphy warned on X. 'As conditions worsen, we urge residents and visitors to avoid wading and swimming in the ocean, especially when lifeguards are off duty.' New Jersey beaches affected include: Asbury Park, Avon-by-the-Sea, Bay Head, Belmar, Bradley Beach, Margate, and Wildwood on the Jersey Shore. The Island Beach State Park will also be closed through Thursday. In a press conference, Murphy said that the hurricane is a 'weird dynamic' as the surf won't necessarily look dangerous, but the rip tides will be. The governor also warned that the state faces a high risk of flooding as the storm approaches. Delaware officials announced swimming prohibitions in Dewey Beach and Fenwick Island. Rehoboth Beach also issued a hazard warning to locals and tourists visiting the popular beach city. 'Due to high winds and heavy surf conditions, the Rehoboth Beach Patrol is prohibiting swimming today under a red flag advisory,' the city wrote on Facebook. 'The heavy surf and increased rip tides will likely continue to increase through Thursday.' Hurricane Erin began as a tropical wave out on the Cabo Verde Islands on August 11, but progressed to hurricane status by August 15. While the hurricane is expected to stay hundreds of miles offshore, it is predicted to intensify as it heads north closer to the US mainland, according to USA Today.

Hurricane Erin could bring dangerous seas as it grows near the Bahamas
Aug 18 (Reuters) - Residents in the Bahamas and Turks and Caicos on Monday braced for the Atlantic season's first hurricane, the Category 4 Erin, after it strengthened over the weekend while sweeping past Caribbean islands. While Erin is not on track to make direct landfall and has yet to cause major damage, its growing size and strength are threatening rough seas and have prompted some evacuation orders in parts of North Carolina, on the U.S. East Coast. "Erin's already large size and intensity are acting like a giant plunger on the sea surface," AccuWeather senior meteorologist Alex Sosnowski said in a report. Sosnowski said Erin was among the fastest-strengthening storms on record after it intensified from a tropical storm to Category 5 hurricane, the highest level of the Saffir-Simpson scale, in just over 27 hours. It makes 2025 the fourth straight Atlantic season with at least one Category 5 storm. The U.S. National Hurricane Center said Erin was expected to strengthen somewhat on Monday as it sweeps by the Bahamas and Turks and Caicos. It will likely maintain its force as a dangerous major hurricane through the middle of the week, but avoid contact with Bermuda or the U.S. coast. As of Monday at 1800 GMT, the storm was packing maximum sustained winds of 140 mph (225 kph) as it skirted north of Hispaniola, the Caribbean's most populous island. Its strength fluctuated over the weekend, rising on Saturday to Category 5 before dropping back to Category 4 late on Sunday. It is the fifth named storm of the 2025 Atlantic season and the first to reach hurricane status. The last Atlantic storm to reach Category 5 intensity was Hurricane Milton in October last year. In Turks and Caicos, an overseas British territory, authorities suspended public services on its largest island and told residents in vulnerable areas to pack in case of evacuation. The Bahamas' meteorology department said the islands' southeast, as well as Turks and Caicos, were experiencing tropical storm conditions, and warned that boats should not go out to sea until the end of the week. "The seas could become extremely rough and dangerous during the swells," it said. Kate Williamson, a Bahamian southeastern district administrator, told local media that the small population living on the eight-square-mile island of Long Cay should move to the mainland and residents finalize their storm preparations. Even though Erin's eye was forecast to stay well offshore, tropical storm conditions and coastal flooding were possible in North Carolina's Outer Banks, beginning late Wednesday, the NHC said. Erin could also produce life-threatening surf and rip currents along much of the U.S. East Coast. Evacuation orders have been issued for parts of two North Carolina coastal counties, with forecasters predicting waves up to 20 feet (6.1 m) and dangerous rip currents on Wednesday and Thursday. Two counties - Dare and Hyde - ordered tourists and residents to leave flood-prone barrier islands of Hatteras and Ocracoke islands. While the narrow islands have just a few hundred year-round residents, about 2.7 million tourists flock to the Outer Banks each year, mostly during the summer, according to the U.S. National Park Service. County officials warned anyone who might consider staying put during the storm that they should not count on getting any help from authorities, due to inaccessible roads. At the Atlantic Inn on Hatteras Island, owner Holly Andrzejewski said that she, her husband and a few employees were going to ride out the storm and keep a watch on their 10-bedroom inn. "Visitors are supposed to leave today," she told Reuters by telephone on Monday and residents are supposed to leave tomorrow. But we're staying. We want to safeguard our property." On nearby Roanoke Island, also in Dare County, no evacuation orders were given as of late Monday, but that could change, said innkeeper Lee Brickhouse of the Roanoke Inn. "Some guests are rescheduling, and we're just holding our breath that the worst won't happen," Brickhouse said.

Hurricane Erin: Category 3 storm could impact entire East Coast
Erin, which remains a major hurricane, is the fifth named storm of the Atlantic hurricane season and the first to reach hurricane status. On the forecast track, the core of Erin is expected to pass to the east of the Turks and Caicos Islands and the southeastern Bahamas late on Aug. 17 and on Aug. 18. The meteorological services of France and the Netherlands discontinued tropical storm watches for St. Martin, St. Barthelemy and Sint Maarten, the NHC said. Forecasters eye two potential storms in addition to Hurricane Erin Rough ocean conditions will likely cause life-threatening surf and rip currents, the NHC said. U.S. shores are unlikely to see a direct hit, but a strong offshore hurricane can produce massive and dangerous waves well away from its center, AccuWeather Lead Hurricane Expert Alex DaSilva said. "The storm is forecast to remain hundreds of miles off the East Coast," DaSilva said, adding that "beaches along the entire East Coast, from Florida to New England and Atlantic Canada, will likely experience rough surf and dangerous rip currents as Erin tracks north and eventually northeast." Hurricane Center director Michael Brennan said 50-foot waves could occur near the center and to the right of Erin as the storm moves northward, resulting in large breaking waves at beaches along the coast. Wave heights, long period swells and life-threatening rip currents - powerful currents of water that can rapidly carry swimmers out to deeper waters - are expected to increase along East Coast beaches by Aug. 18, according to the hurricane center and local National Weather Service offices. Even from far offshore, "the threat for life-threatening rip currents, damaging beach erosion, major coastal flooding and extremely dangerous surf is increasing," the National Weather Service office in Morehead City, North Carolina said on Aug. 17. Wave heights could range from 12 to 20 feet along the Outer Banks, the office reports. A high risk of rip currents is forecast along some areas of the Atlantic Coast from Aug. 18 through Thursday, "a big threat," according to the weather service office in Jacksonville, Florida.
