Rain.
Had a couple off days of rain but the past 24 hours? Well - had 82cm of rain, wind gusts up to 104kph, thunderstorms...⛈️ 💨The low-pressure system that deepened off the coast is supposed to move away soon - thank goodness!
My water tank (which was empty) is overflowing despite doing three loads of washing.
See that tiny red splotch (indicating really heavy stuff) - that's where I live 🚣‍♂️

#Water shipped into #Skerries with levels low

Prolonged periods with minimal #rainfall left the reservoir and storage tank levels low in Skerries, #Scottish Water said.

That has meant the company is having to ship a road tanker full of treated water into the #island up to five times a week from #Whalsay to maintain people’s #water supplies.

Scottish Water said this would “continue for the foreseeable future”.

#ExtremeWeather is the #UK's new normal, says Met Office

Justin Rowlatt, July 13, 2025

"The UK is breaking #heat and #rainfall records increasingly frequently as its climate continues to warm, the Met Office has warned.

"The country's changing weather patterns mean the UK now experiences a 'notably different' climate to what it was just a few decades ago, its State of the UK Climate report says.

"We now have many more very hot days and many fewer extremely cold nights, according to this latest assessment.

"It shows just how much #GlobalWarming caused by the vast emissions of #GreenhouseGases our civilisation creates is reshaping the country's climate.

"Climate change is bringing more #SevereWeather events like #storms and #flooding - and inevitably the country's changing climate is having an impact on the #NaturalWorld, with some species suffering.

"The report focuses on 2024, when the UK experienced its second-warmest February, warmest May, warmest spring, fifth-warmest December, and fifth-warmest winter since records began in 1884.

"The Met Office highlights that some of these records have already been surpassed in 2025 - more evidence of this trend towards more extreme weather.

"This summer many parts of the country are in the throes of their third heatwave with very warm weather reaching into #Wales, #NorthernIreland and #Scotland as well as southern #England."

Two missing as heavy rains hit Catalonia.

Two people were missing Saturday after torrential rains and floods in Catalonia in northeastern Spain.

Firefighters said they were searching along the banks and mouth of the Foix river for two people who went missing near the town of Cubelles, about 50 kilometres from Barcelona.

The torrential rainfall has also disrupted transport services in and around Barcelona.

Looking for a map of areas of Scotland prone to flash flooding. Specifically interested in the Tay but even a nationwide one would be good. Not just tidal flooding but flooding related to projected increased rainfall. #ClimateDiary #ClimateChange #EmergencyPlanning #map #Scotland #rainfall
Quick edit: I have the SEPA maps, Fife Council maps and the coastal flooding maps. I’m specifically looking for increased rainfall predictions in relation to flash flooding risks.

Over half of Europe and Mediterranean basin hit by drought in mid-May

The European #CentralBank warned on May 23 of major #economic risks from drought, which can threaten up to 15% of production in the #eurozone due to increasing #ExtremeWeather caused by climate change

More than half, or 53%, of land in #Europe and the #Mediterranean basin were hit by #drought in mid-May, according to an #AFP analysis of data from the European Drought Observatory (#EDO) from May 11-20, 2025.

It was the highest level recorded for that period of time in the year since monitoring began in 2012, and more than 20 points higher than the average between 2012-2024.

The EU's #Copernicus #ClimateChange Service, based on #satellite imagery, takes into account three benchmarks: #precipitation, or #rainfall, soil #moisture and the state of #vegetation.

Effective emergency management prevented larger catastrophe after climate change fueled heavy rains in Central Mississippi river valley

The #floods inundated large rural areas including agricultural fields, especially in #Arkansas which has resulted in an estimated 78 Million USD of damage due to losses in fields that were already planted. Larger losses were avoided due to the timing of the floods before other #crops like #peanuts and #cotton were planted, and since there is still a window to replant crops like #corn and #soybeans.

Based on gridded data products, we find that the extreme #rainfall event over the study region is relatively rare, expected to occur in today’s #climate only once every 90-240 years across different observational and reanalysis datasets. However, in a 1.3°C cooler climate, extreme rainfall such as observed would be even rarer. The best estimates for the increase in likelihood for the 2025 event associated with this warming is between a factor 2 to 5, and the increase in intensity for an event of equivalent rarity as observed is 13-26%.

To quantify the role of human-induced #ClimateChange in this increased likelihood and intensity we also analyse climate model data over the study region for the historical period. The best estimate of the synthesised result, combining observations with climate models, is about a 40% increase in likelihood and about a 9% increase in intensity. These estimates are smaller than the observed trends due to large discrepancies between the climate model results. While some models show increases similar to or larger than the observed trends, others show weaker or even decreasing trends.

In contrast, #ClimateModels consistently project that extreme precipitation events such as the one observed in April 2025 will become more frequent and intense in the future as global temperatures rise. Under current climate policies – which will lead to warming of approximately 2.6°C by 2100 – such extremes are expected to approximately double in likelihood again, and increase in intensity by about a further 7%.

As the moisture that fuelled the rainfall event was partly coming from the #GulfOfMexico we also assessed the role of climate change in the sea surface temperatures. We found that these waters were heated by approximately 1.2 °C (2.2 °F) due to human-caused climate change, and such #ocean conditions are now about 14 times more likely than in a cooler pre-industrial world. This contributed to higher #evaporation rates, increasing the availability of moisture in the rainfall event.

The strong observed trends in precipitation extremes in this region are also found in other studies using different methods, across different regions, including the Central #Mississippi river valley and are assessed as being attributable to climate change by the #IPCC AR6 report.

In conclusion, due to (1) the observed trends that are (2) in line with IPCC assessments and other literature in the region, and (3) the clear emergence of a climate change signal with further #warming in all climate models as well as (4) the availability of more moisture due to higher SSTs, we state that climate change amplified the heavy rainfall leading to the floods and that the estimate from observations and models combined of a 9% increase in intensity and 40% increase in likelihood is conservative and the role of climate change could be as large as the observations alone suggest

Despite being an extremely complex event, with tornadoes, flash floods, riverine floods and landslides overlapping, the US National Weather Service made a tremendous effort to provide early warnings for the floods, in some cases up to a week in advance of river crests. These early warnings allowed state and local emergency departments to prepare, inform the public, and evacuate those at highest risk. While any loss of life is devastating, the outcomes of this event point to the effectiveness of decades-long investments made in forecasting, #EarlyWarningSystems, and #forecast-based action.

Nearly half of NWS field offices are facing vacancy rates of 20% or more, double the short-staffing levels of a decade ago. Former NWS leaders have recently warned that layoffs could impact the ability of NWS offices to respond to extreme weather events and keep people safe.

I am so sick of rain!
The east coast of NSW has been inundated with a 500 year flooding event. An East Coast Low has cause it all.
The map attached only show the areas where I live, thankfully I live on a slight hill (blue dot) and at the moment it's "Watch & Act" but it's really bad.
I have a small weather station in my yard and have had over 460mm (18") of rain since Saturday morning - & it's still raining.
It's supposed to start clearing on the weekend.
Sadly four people have died and over 50,000 people have been evacuated. Thousands are isolated.
