Over 80 major fires are raging across the US and serious flooding has hit India and New Zealand in a spate of extreme weather events to emerge around the world in the wake of devastating floods in western Europe last week.

The enormous Bootleg fire in Oregon grew again on Sunday with oppressively hot and dry weather looming over much of the western US and Canada.

The largest of 80 major fires now active in the US, the Bootleg fire spread overnight from 274,000 acres to 290,000 acres – nearly the size of Los Angeles, officials said. Over 2,000 people have had to evacuated from the affected area.

Satellite imagery from the National Weather service showed a huge plume of smoke soaring from Bootleg, in southern Oregon, to the Canadian border, hundreds of miles to the north-east.

But, with firefighters making progress on Bootleg’s western flank, overall containment of the blaze more than tripled, to 22 per cent.

Firefighters also blamed lightning strikes for a fast-growing blaze in California’s Lake Tahoe tourist area. The so-called Tamarack Fire, fanned by fierce winds, has grown explosively to more than 20,000 acres, with zero containment so far. The small nearby community of Markleeville, on the Nevada border, has been evacuated.

The National Interagency Fire Center said nearly 20,000 firefighters and support personnel are struggling to contain fires raging across the western states, with more than 2.5 million acres having already burnt this year.

Firefighters in Canada, meanwhile, continued to battle dozens of blazes, including some 20 new fires in British Columbia and around 15 in north-west Ontario.

Separately, India’s capital New Delhi and the main financial centre of Mumbai were drenched with heavy rain on Monday, a day after at least 35 people were killed across the country in landslides and house collapses triggered by downpours.

The Indian Meteorological Department has predicted heavy to very heavy rain in north India over the next two days. In Mumbai, the IMD has issued a heavy rain and thunderstorm alert for the city and surrounding districts.

At least 30 people were killed on Sunday in three Mumbai suburbs when several houses collapsed in landslides after rain. At least three people were also killed when a house collapsed in the northern state of Uttarakhand after a downpour.

In a separate incident on Sunday evening, a three-storey building collapsed in the city of Gurugram, bordering Delhi. Two people were killed and rescue operations were still underway.

Several low-lying areas of Delhi and Mumbai were flooded and images have emerged of submerged vehicles and people wading through waist-deep water.

Mumbai’s water treatment plant in the suburbs was flooded on Sunday forcing the municipal council to impose water cuts in some parts of the city.

India is in the midst of its annual rainy season but the downpours over the past few days have been particularly heavy.

Extreme weather has hit several parts of the world in recent days, with flooding also bringing parts of New Zealand’s west coast to a standstill.  

Around 300mm of rain fell over a single weekend across parts of the west coast – around a typical month’s amount concentrated in two days. The rainfall caused rivers to break their banks and more than 2,000 residents were evacuated. 

The extreme weather events come in the wake of some of the worst flooding in recent memory across parts of western Germany, Belgium and the Netherlands last week.

The death toll from the floods in Germany rose to 165 on Monday, as emergency services continued to comb through decimated towns in search of dozens of people still missing.

A total of 117 are now confirmed to have died in the German state of Rhineland-Palatinate, while 47 victims were recorded in the neighboring state of North Rhine-Westphalia and one in Bavaria. At least 31 people have died in Belgium.
