What is frost?
Frosty nights are likely to get more prevalent as we head further into autumn, but what exactly is frost and how is it measured? BBC Weather's Alex Deakin has the answers...
Heavy rain and strong winds from Tropical Cyclone 02B brings the threat of flash flooding to many low-lying parts of Bangladesh, Myanmar and Northeast India. The recent withdrawal of the southwesterly monsoon was significantly delayed. BBC Weather's Susan Powell has the details. Winds of up to 70 miles an hour churned up a cloud of red dust almost 1.5 miles high during a dust storm at a town in Texas. The number of people killed in Central America by floods and landslides, has risen to at least 80, officials say. More stormy weather forces another halt to efforts to pump oil off a leaking grounded cargo ship. The BBC's Rachel Harvey has flown over some of the worst-affected areas in Thailand to see the extent of the damage.
