For 10,000 visitors, a supertide in France did not disappoint as it immersed the only connecting point of Mont Saint-Michel (N france) to shore. It inundated the area near Mont Saint-Michel and created a short-lived island as overflowing water made the causeway impassable. Once every 18 years, experts say a supertide cuts off the only access point, one thin strip of road, to a the home of medieval structures. Drawing more than 3 million visitors a year, UNESCO named Mont Saint-Michel a World Heritage Site. The supertide occurs when the path of the earth, moon and sun are all very closely aligned in their orbits.

Tropical cyclone Nathan has crossed the Northern Territory coast (Australia) as a category one cyclone. It hit the coast about 300km east of Darwin between Goulburn Island and Maningrida about 6.30am. A state of emergency has been declared on Goulburn Island, and all 427 residents were flown to Darwin on Monday on 51 flights before gale-force winds picked up. At 6.30am, the Bureau of Meteorology said Nathan was about 45km east-south-east of Goulburn Island and 45km west-north- west of Maningrida, moving south-south-west at 6km/h. Winds near the centre of Nathan are 75km/h with gusts to 100km/h.

Flash floods in one of the driest regions in the world - Chile's Atacama desert - have left two people dead and 24 missing. Thousands of people are now without electricity or water, as heavy rains in the Andes sent floodwater down into the valleys and towns below. In the city of Copiapo, the river burst its banks. The storms, which began on Tuesday evening, have cut off roads, caused power cuts and severed communications. Local officials say 38,000 people are without electricity and 48,500 without drinking water.

Several tornadoes touched down across areas of Arkansas and Oklahoma, including Moore, late Wednesday afternoon. One person died after a storm hit a mobile home park near Sand Springs, Oklahoma.
