Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new article suggests.

Scientists have discovered an underlying repeatable pattern in how space weather activity changes with the solar cycle - having analysed solar activity for the last half century.

The annual Perseid meteor shower peaks tonight, so many of us will be out under the skies observing this fine celestial show. Weather permitting, of course. So let us take a look across Europe what the weather will be like for the Perseids. The current weather pattern across Europe reveals a deep trough over NNE Europe with a another trough over WSW Europe, while a shallow ridge dominates east-central Europe and Balkan peninsula. Should be cloudy in some areas (W Europe), but expect gradually clearing skies in the evening over other parts of Europe, after daytime convective activity diminishes. So great chances for many observers across our continent. Tonight, August 12/13 We take a look over the cloud coverage in

The annual Perseid meteor shower peaks this weekend, so many of us will be out under the clear skies observing this fine celestial show. Weather permitting, of course. So let us take a look across Europe, what the weather will be like for the Perseids. The current weather pattern across Europe reveals a flattening strong upper ridge over east-central Europe as a deep trough from western Europe is pushed towards north Europe tonight. This brings a cold front with colder airmass across central Europe, so the weather will be cloudy in some areas, but expect gradually clearing skies in the evening, after daytime convective activity diminishes. Tonight, August 10/11 We take a look over the cloud coverage in the low/mid-level

North Europe will see a partial Solar eclipse on August 11. The eclipse will visible in Iceland, Norway, Sweden, Finland, Estonia, Latvia and NW Russia. The best place to see the exlipse will be the extreme north of Norway and Svalbard Island. The eclipse happens between 8:30 UTC and 10:00 UTC. The southern limit of eclipse runs across the northernmost part of Scotland, extreme south of Norway, southern Sweden and central Latvia. Iceland will see about 20% maximum eclipse, as will northern Sweden and central Finland. The northernmost part of Norway will see ~30% maximum eclipse. Svalbard will see about 43-44% eclipse. Map of August 11, 2018 partial Solar eclipse by NASA. 0.20 = 20% eclipse, 0.40 = 40% eclipse,

As expected, western and central Europe were hit by severe thunderstorms today. Storms with severe straight line winds, large hail and torrential rainfall, causing flash flooding, were reported in parts of France and Germany. Thunderstorms with severe straight line winds and large hail were reported in the morning and early afternoon in central and northeastern France. Meanwhile, persistent training storms produced major flash flooding in parts of southern and southeastern France. Lightning tracks across western Europe on August 9: note the continuous tracks starting over W France and continuing across central France into BeNeLux and Germany, produced by organized thunderstorms / squall lines. Lots of activity in southern France, where training storms produced persistent torrential rainfall and flooding. Also some

The cyclone associated with the trough and frontal system passing across western and central Europe today will also produce unseasonally strong non-convective winds in BeneLux, northwest Germany and – in particular – in Denmark. Winds gusting up to ~130 km/h are possible. The low will pass across BeNeLux today, crossing into the eastern North Sea and rapidly deepening to a central (MSL) pressure below 1000 mbar by late morning tomorrow. At the time it will likely produce strong winds gusting up to 120-130 km/h along the western coast of Denmark. Peak wind gusts indicated by ARPEGE and ICON-EU models. Maps: Wxcharts.eu

Another focus for today’s convective activity across Europe will be a part of Scandinavia where severe storms with damaging winds and tornadoes are likely this afternoon. While the northeastern Europe is under an extensive strong ridge, a short wave trough with a surface front slides across N Scandinavia on the western edge of the ridge. This allows a corridor of strongly shear environment and forcing for storm development across south-central Finland by mid-afternoon hours. 500mb chart across Europe reveals a strong jet stream rounding the large upper trough over E Atlantic while strong ridge is placed over ENE Europe. The tight pressure gradient between the two brings a strong shear across France, N Germany up across Scandinavia. With all the

Today, Thursday Aug 9th, a dangerous setup is shaping up for E-SE France, E Benelux, W-SW and N Germany into S Denmark. Ahead of an approaching deep trough over the E Atlantic, a negative tilted short-wave trough is pushed across N France, providing large scale forcing/lift for widespread convective activity. Moderately unstable boundary layer will overlap with strong to very strong shear, so strongly organized severe thunderstorms are expected, capable of producing large hail, severe damaging winds, torrential and locally excessive rainfall. In addition, some tornado threat is possible as well, especially across far NE Benelux and N Germany towards the evening hours. While strong convective activity is already ongoing across France where large storm clusters have initiated in the

A damaging debris flow hit the village of Chamoson, Switzerland late afternoon yesterday, August 7. It was caused by locally very intense rainfall, with surface runoff streaming into a channel in Chamoson. Preliminary reports indicate 18 mm of rain fell in only 10 minutes and a total of ~50 mm in one hour. The reported data however, is from a weather station several kilometers away so locally there may have been even more rainfall. Debris flows are a form of water-saturated mass movement, typically caused either by short, intense ranifall. Depending on the amount of bedload suspended in the flow, such events range from flash floods (with relatively little bedload) through hyperconcentrated flows to debris flows.

Mark your calendars for a spectacular celestial fireworks display this weekend! The Perseid meteor shower peaks on Sunday, and with no Moon in the sky this could be the best meteor display in quite some time. The Perseid meteor shower is one of the finest and most reliable annual meteor showers. On their peak night the Perseids make a spectacular fireworks display with up to, and sometimes over 100 meteors per hour. What is a meteor shower? Why does it happen? Meteors are light phenomena that occur when small dust particles, called meteoroids, impact the Earth’s atmosphere at tens of kilometers per second and burn up. These meteoroids are tiny bits and pieces of asteroids and comets. You can see

Researchers have designed a computer model that more effectively calculates the behavior of atmospheric turbulence in complex environments, including cities, forests, deserts and mountainous regions.

Oregon, one state above California, is also having its share of fire storms and weather concerns. Five large fires/complexes are alight in the southwest corner of the state and all started on the same day with a region-wide lightning storm.

Very hot weather continues across parts of western and central Europe today as strong warm advection takes place ahead of an approaching trough from the eastern Atlantic. Temperatures will be in the upper 30s, approaching 40 °C in parts of France, up to +38 °C across Benelux and Germany. Southern Iberian peninsula gets the tail end of the ongoing heat wave today, with temperatures again above 40 °C. Heat in this region will be ending this evening as a cold front pushes from the western Europe, bringing an outbreak of severe storms across N France and Benelux and good refreshment with much colder airmass in their wake. France, Benelux and Germany Large parts of France will get well above 35

The overall blocking “heat wave pattern” across Europe is changing this week, as a more progressive pattern develops. A large deepening trough is placed across the E Atlantic while an upper ridge remains over ENE and N Europe. In between, a corridor of strong warm/moisture advection brings unstable airmass ahead of the cold front and favorable conditions for development of severe storms. The first day of active storms will be today, Tuesday Aug 7th, across N France, Benelux and NW Germany. Strong instability and moderate wind shear overlap and an outbreak of severe storms is expected in the late afternoon, evening and night hours. A quite impressive moisture recovery takes place beneath an EML plume from SW Europe across France

Flooding caused by rain falling on snowpack could more than double by the end of this century in some areas of the western United States and Canada due to climate change.

The effects of global climate change taking place in the Arctic may influence weather much closer to home for millions of Americans, researchers report.

Very hot weather continues across much of western and parts of central Europe today. Temperatures will be in the upper 30s, approaching 40 °C in parts of France and Italy. Southwestern Iberian peninsula gets the tail end of the ongoing heat wave today, with temperatures again above 40 °C. France Large parts of France will get well above 30 °C today. Central France, parts of southern and extreme southwestern France will peak up to 36-37 °C. Especially southwestern France will likely push up to 38-39 °C. Italy North and central Italy wil push into upper 30s today. Peak temperatures are likely to reach 36-37 °C. In addition, the airmass in the plains of north Italy will be very humid, with

We have just ended an interesting week with record breaking and extreme heat wave across Iberian peninsula. This coming week will bring additional heat into parts of central and eastern Europe, but also a good refreshement in the second half of the week as a deep trough develops across E Atlantic and pushes a cold front towards east. In addition, a lot of severe weather is expected from France and Benelux on Tuesday across central Europe from Wednesday through Friday. See details below. A new week starts with a deep trough over N Scandinavia which brought a much needed refreshement for the region which was experiencing severe heat wave in the past weeks. Further south, a record-breaking heat wave and

The intense heat wave in the southwestern part of the Iberian peninsula continues. For three days in a row now temperatures have peaked at 46-47 °C. Today will be hot again, with peak temperatures just slightly lower than in the past days. This has been an very intense heat wave for parts of Spain and Portugal. While it did not break the all time European record, temperatures climbed to 46.6 °C on Friday. Yesterday pushed up to at least 46.6 °C, we will be posting an analysis shortly. Today will be another very hot day, however, peak temperatures will likely be about a degree or so lower than the past few days. Expect peak temperatures around 44-45 °C. The hottest
