Tropical storm Karen is one of three storms currently forming or dissipating in the Atlantic Ocean. The latest crop of weather systems come after an active hurricane season in the Atlantic, where severe weather activity has exploded in the last month. Atlantic hurricane season traditionally runs from June to November every year, but most activity arises in the second half of August. Karen has come during the Atlantic’s most active period, and with it could bring some strange weather patterns.
Tropical storm Karen is currently moving near Bermuda with maximum sustained winds of 45mph.
As it strays towards the island, it could come into contact with the Bermuda-Azores High, a semi-permanent centre of high atmospheric pressure.
The storm could then lose the steering winds it needs to continue on a discernible path, making it difficult for computers to predict its movements.
Karen could then veer to the east, and build in strength as it comes into contact with pressure from an early Autumn heatwave building over the US.

The same area of pressure could also pull on the system, and drag it back towards the US, which has happened in the past.
The last time a storm rounded on the US after dwindling in the Bermuda Triangle was in 2004 with Hurricane Jeanne.
Jeanne was an intense storm which levelled Haiti and killed 3,000 but weakened over the Bermuda Triangle after land interaction.
High pressure from a second hurricane named Ivan slung it back to the US at Florida where it made landfall as a Category 3 hurricane.

While history could well repeat itself with Karen, but according to the National Oceanic and Atmospheric Administration (NOAA), it will drift out further than the 2004 system.
The National Hurricane Centre (NHC) said: “At 500 AM AST (0900 UTC), the centre of Tropical Storm Karen was located near latitude 20.5 North, longitude 65.2 West.
“Karen is moving toward the north near 14 mph (22 km/h), and this general motion is expected to continue this morning.
“A motion toward the north-northeast is forecast to occur by this afternoon and continue through Thursday.”

“On the forecast track, the centre of Karen will continue to move farther away from Puerto Rico and the Virgin Islands today through Thursday.
“Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
“Some strengthening is forecast during the next 48 hours.
“Tropical-storm-force winds extend outward up to 70 miles (110 km) from the centre.”
