Turkey - Residents of Samsun in Turkey’s Black Sea region used boats to cross streets after heavy rainfall caused flash flooding in the city. No casualties have been reported yet. The city was also hit by floods last week, which resulted in at least two deaths.

UK - Flash flooding and lightning strikes have caused severe disruption across Greater Manchester and Lancashire. Torrential rain at Manchester Piccadilly created significant delays for rail passengers on Monday evening while roads were flooded in Salford and Manchester Airport saw planes diverted. Manchester City's victory parade was also delayed due to the intense storm.

El Niño - El Niño is back, and it could push the world past a new average temperature record. The global weather phenomenon refers to when waters in the Pacific Ocean become much warmer than usual. After three years of the cooling La Niña weather pattern, the US National Oceanic and Atmospheric Administration (NOAA) announced on Thursday that El Niño is now underway.

El Niño pushes warm water in the Pacific Ocean eastwards, causing the Pacific jet stream to move south of its neutral position. This produces dryer and warmer weather in northern US and intense rainfall and flooding in the US Gulf Coast and Southeast. In Europe, it can lead to colder, drier winters in the north and wetter winters in the south. Indonesia and Australia will likely experience hotter and drier weather with a greater possibility of wildfires. Monsoons in India and rains in South Africa might be reduced while east Africa could get more rains and flooding. El Niño also increases hurricane activity in the Pacific meaning places like Hawaii will be at risk of tropical cyclones.

During the phenomenon, the global temperature increases by around 0.2 degrees Celsius, according to NOAA while the Eastern-Pacific sea surface temperatures will be at least 1.5 degrees Celsius higher than normal.
