While recovering from the heatwave: and update on soil moisture, groundwater levels and water usage restrictions put in place in France and Belgium [part 1: https://twitter.com/FlorianDRX/status/1124734200937054208]

What are long term evolutions, how did it change since April?

On heatwaves: evolution = clear https://t.co/QjBvukuJle

Long-term precipitation:

3-month Standard Precipitation Index [4/5/6] ↘️ since 70s in FR [Puy-de-Dome] and BE [Antwerp]

Monthly rainfall ↘️ in FR & BE

SPI = number of st. dev. by which the observed anomaly deviates from long-term mean https://t.co/477FtrpHts

Water situation in France: Auvergne-Rhone-Alpes [update: 1 June] @auvergnerhalpes

FR - Rainfall

Precipitation is 13 % below the long-term average, 13th driest month since 1959 http://bit.ly/309knhC https://t.co/fyKOEnSCWM

FR - Soil drought [update https://twitter.com/FlorianDRX/status/1124750222675066881]

*Deficit up to 60 % in large parts of the region https://t.co/bldNFvvPUo

FR - Streamflow [update https://twitter.com/FlorianDRX/status/1124750554167750658]

*Globally depressed streamflow: a majority of test points has an average flow rate below the ‘Five-Year Dry Flow’ [= monthly flow with a 4/5 probability of being exceeded each year] https://t.co/i42BakmXwN

FR - Groundwater levels [update https://twitter.com/FlorianDRX/status/1124750801610653698]

*Low groundwater levels in majority of the region http://bit.ly/2NrUyYL https://t.co/tvrr2CFqnz
