There have been 9 Flash Flood Emergencies issued in the last 7 days in the U.S. The average is 3 per month. There were a record 92 Flash Flood Emergencies in 2024, nearly 3 times the annual average since the alert was first implemented in 2003.
Extreme weather events (flash floods, tornadoes, damaging winds, large hail, extreme heat waves and droughts) are increasing rapidly in frequency, intensity, and duration. This is associated with the rapidly degenerating polar jet stream in the northern hemisphere which is due to a huge increase in disparate warming in the Arctic which had surface air temperatures + 10 to + 15 degrees C (+ 18 to + 27 degrees F) above the average for the date for 3 months running. The polar jet stream is slowing in eastward speed, wobbling more, becoming more chaotic, shredding, and becoming increasingly meridional (north -south) – causing increasing weather wilding and weather whiplash.
Heavy precipitation events are also increasing due to rising sea surface temperatures in many parts of the world but so are droughts and overall the continents are getting drier.
The worst flooding by far has been in parts of China where rain has been virtually relentless for the last two months (photo).
All of these trends are due to accelerating global warming. Anthropogenic greenhouse gas emissions are higher than ever now.

The quality of China’s domestic disaster response has been greatly improving (and they’ve had lots of practice), and will make the remnants of FEMA look like a joke.
Meanwhile in Ozstralia, first half 2025. Massive and extensive Record-Breaking floods in the NE with inland sea size salt pans becoming lakes. Just to highlight the weather extremes, the SE of the continent, not really that far away, was in severe drought at the same time. My state of South Australia had its dryest 6 month start to the year Ever recorded.
