The peak of the 2019 Atlantic hurricane season has now passed, but tropical systems have continued to develop with no sign of stopping. So far, there have been 13 tropical depressions, 12 tropical storms, five hurricanes and two major hurricanes this season. There are three storms are currently churning across the Atlantic and according to the latest spaghetti models are potentially on a course to collide.
The phenomenon of two hurricanes colliding is called the Fujiwhara effect.
When two cyclones pass within 900 miles of one another, they can start to orbit.
However, if two storms get to within 190 miles of each other, they can collide or merge, turning the smaller storms into one gigantic superstorm.
In rare instances, close proximity can throw a storm off course, as was the case with hurricanes Hilary and Irwin in July 2017.

When two or more storms get within a certain distance of one another, what happens next is determined by the size of each storm.
If one storm is much stronger than the other, the smaller storm usually rotates around the larger one.
However, when both storms are similar in strength, they tend to orbit a common centre between the two.
According to the spaghetti models for Hurricane Lorenzo, tropical storm Karen and post-tropical cyclone Jerry, it is possible these three whirling twisters will crash into one another.

Currently, Hurricane Lorenzo is located at latitude 14.1 north, longitude 35.1 west, roughly 715 miles west of the southernmost Cabo Verde Islands.
The storm is moving west northwest at 17mph and is predicted to continue this motion through early Thursday before it begins to head northwestwards on Thursday through Friday.
Lorenzo is forecast to strengthen into a hurricane by Wednesday and a major hurricane, meaning at least a Category 3 storm with wind speeds of 111mph to 129mph.
According to the National Hurricane Center, Lorenzo is expected to reach a maximum wind speed of around 121mph on Saturday.

Currently, the storm has maximum sustained winds of 85mph, making it a Category 1 hurricane and it is moving west northwest at 17mph.
Tropical storm Karen is continuing to thrash Puerto Rico, Vieques, and the US and the British Virgin Islands with heavy rain causing flash flooding.
It was expected to resume a motion towards the north yesterday afternoon and then proceed with a north northwestward motion through Wednesday.
On the forecast track, the centre of Karen would pass near or over Puerto Rico and the Virgin Islands yesterday afternoon and then move over the western Atlantic on Thursday.

A slow strengthening is expected during the next few days, with winds currently recorded as 45mph, with tropical-storm-force winds extending outward up to 70 miles, mainly to the southeast of the centre.
Karen is expected to reach a maximum wind speed of 69mph on Saturday and Sunday.
The final storm which is on a collision course to crash with these other storms is post-tropical cyclone Jerry which is tracking at latitude 32.0 north, longitude 66.8 west, about 120 miles west of Bermuda.
The storm is moving towards the east northeast at around 10mph.
The centre of the storm is anticipated to pass near Bermuda on Thursday.

Gradual weakening of the maximum sustained winds is forecast during the next few days.
Tropical-storm-force winds extend outward up to 140 miles (220km) from the centre.
Jerry, now a post-tropical cyclone, is currently moving at 10mph and is Jerry is expected to reach a maximum wind speed of 40mph on Thursday.
The spaghetti models for the three storms reveal it is possible for the three to crash into each other.
According to these charts, the most likely sequence of events for an impact hit between these three storms is Karen crashing into Jerry first, before Jerry hits Lorenzo.
However, the likelihood is that tropical storm Karen will collide with post-tropical cyclone Jerry, while Lorenzo turns and moves towards the UK.

Elsewhere in the Atlantic, there is a weak area of low pressure located just offshore of the northwestern coast of the Yucatan peninsula is producing limited shower activity.
Significant development of this system is not anticipated while it moves westward at about 5mph across the southwestern Gulf of Mexico.
The disturbance is expected to move inland over northeastern Mexico on Saturday.
The chance of formation of this disturbance is low, at only 10 percent, through 48 hours to five days.
If the storm does develop, it is possible it could in fact track towards the other storms in the Atlantic, crashing into the three currently whirling across the Atlantic.
