High winds swept across Bermuda at the weekend causing an unusual incident with a trampoline for one family.Sally Topley, 45, was convinced a tornado had swept through her back garden in the early hours of Saturday after she woke to find her children’s trampoline on top of some 15ft trees.The 14ft round trampoline a recent Christmas present for Joshua, seven; Benjamin, five; and Meghan, three was later brought back to earth using ropes by Mrs Topley’s husband and a friend. Its mat had been pierced by a cedar tree.Mrs Topley, of Store Lane, Sandys, said: “It was bizarre. All was calm, then suddenly torrential rain, deafening high winds and lightning occurred around 1am...then after a few minutes complete silence and calm.“When I got up at 3.30am to let my dog out I noticed our heavy trampoline was gone. Took a while before I realised it had blown up and over into a tall patch of trees near our property. It actually was upright.“We have three little birdhouses on our front patio not attached to anything and they were untouched. Very strange. I am pretty certain there was [a tornado].”Meteorological forecaster James Dodgson, from Bermuda Weather Service, confirmed there was a sudden increase in wind speed known as a gust front or squall late on Friday.“A very active area of thunderstorms moved across the Island,” he said, explaining this could have caused strong winds high up in the atmosphere to be brought down to the surface.“These systems can also produce tornadic activity, but this is unlikely in this event, as more widespread damage would have been expected.”He said at LF Wade International Airport the winds went from 23 knots (26mph) at 11.17pm to 32 knots (37mph) with gusts of 50 knots (58mph) at 11.33pm.“This would certainly be enough to blow things over, especially the trampoline, due to its large surface area, which was able to catch the wind and its relatively light weight, considering its size.”The bad weather continued yesterday, as predicted by a gale warning issued late on Friday by forecasters.Mr Dodgson said: “As the event approached, warnings were upgraded, culminating in a storm warning being issued at 10.30am this morning for the rest of the morning and a gale warning running through the afternoon.”He said a peak mean wind speed of 45 knots (52mph) was recorded at the airport at 9.25am and a gust of 59 knots (68 mph) at 9.55am.This caused two flights to be delayed: AA 1443 to JFK left at 12.05pm instead of 9.20am and AA 1325 to Miami departed at 1.30pm instead of 8.10am.A peak gust of almost 75 knots (86mph) was recorded at Commissioner’s Point, Dockyard, at about 9.30am, while there were gusts of 60 knots (69mph) on the Causeway. Both places tend to record stronger gusts due to their exposed wind observing sites.Mr Dodgson said the winds were caused by a rapidly deepening area of low pressure that moved northeast to the Island’s near west yesterday morning.He added that the airport recorded a temperature of 68F (20C) on Saturday night with about 90 percent humidity, later dropping to 59F (15C) with almost 65 percent humidity.“This contrast is a good indicator of a strong winter storm system moving through our area,” said the forecaster.A Bermuda Maritime Operations centre duty officer said the weather caused a couple of boats to take on water at their moorings but there were no major problems at sea. A small craft warning is in place until Tuesday.
