UK and World weather report:
The UK's recent quiet weather took a dramatic turn last week as fog gave way to gales and heavy rain. The foggy start to the week, with visibility down to below 50m in places in the south and east on Monday and Tuesday.
Despite a colder night on Tuesday, with a minimum of - 2.3 °C and widespread ground frost across England and Wales, temperatures remained a little above normal throughout the week, with a high of 15.9 °C at Fyvie Castle in Aberdeenshire on Saturday.
On Thursday, a rapidly deepening area of low pressure moved past the north west of the UK, bringing severe gales over the far north west as well as persistent and increasingly heavy rain that continued into Friday and over the weekend.

Cassley in Sutherland recorded 66.6mm of rain in 12 hours, gales affected northern Scotland, peaking with a gust of 90mph at Fair Isle on Sunday morning. The storms left about 400 homes without power in Orkney, caused landslides, and A cargo ship sunk after reportedly being rolled over by a wave and breaking in two in the Irish Sea.
Elsewhere in the world, heavy rain is continuing to cause problems. In the Philippines, six people were killed in flash floods after continuous rains in the area caused local rivers to overflow. In Australia, floods have left thousands cut off in the town of Wee Waa in New South Wales. The town will only be accessible by boat and helicopter for at least a week.
Meanwhile, Mexico is suffering its worst drought in 70 years. Due to the lack of rainfall the government has forced been to supply water to nearly 2.5 million people across eight states.

By Tuesday, it is expected to lie over the Hudson Bay, with particularly windy conditions on its southern flank possibly affecting coastal Ontario, Manitoba and Quebec.
• Another depression, moving northwards towards the Great Lakes from the Gulf of Mexico over the next few days, will also bring heavy rain to places in between as it passes.
• Cooler than average conditions extending from Saudi Arabia across Sudan, Chad and perhaps even reaching northern Nigeria. Conversely, warmer than average across much of Madagascar.
• A spell of wet weather is expected for Saudi Arabia, Kuwait, Bahrain, Qatar and the northern Gulf on Monday and Tuesday. Rainfall totals of 40-60 mm are likely, with flash flooding a possibility. This is the first significant rainfall since the spring in this area. It is also unseasonably cold, both in this region and more widely across the Middle East.
• Some rather windy conditions likely for Oman, especially coastal regions and particularly later in the week, in association with a deep depression. This is also likely to impact on coastal parts of Karnataka, Kerala and Goa in India for the next day or two.
• Some large temperature variations across southern Australia this week, with south western parts going from cool to warm and south eastern areas swinging from warm to cool.
• Heavy rainfall is set to continue in Australia and Asia due to a La Nina pattern in the Pacific Ocean.
