[Storm Gerrit to imprint the damp end for the UK to what has already been a rather wet 2023] Storm #Gerrit has been named today by the Met Office and Met Éireann due to expected hazardous weather conditions affecting most of the southern flanks of the #RepublicOfIreland spreading southeastbound across #Wales / #Cymru, north-northwestern #England and most of #Scotland. The main concern is the advancement of warmer airmass as #WarmFront pushes a band of heavier #precipitation across Wales northwards, bumping into cold airmass across Scotland and northern England, consequently causing #WinterHazards over the #Pennines, where the orographic factors contribute to the precipitation amplification due to latent heat release and condensation while an air parcel has been lifted and continuously cooled with the cooler air aloft, with potential to #SnowAccumulation up to 10 cm at the highest points. Adverse weather is likely to cause #traffic disruptions due to road spray and reduced horizontal visibility. Apart from the precipitation, severe winds are another threat to normal activities, which is nicely depicted on the wind field (this time the main focus is put on the precipitation). Over the exposed Welsh shores and along the Irish Sea, gusts are expected to reach up to 70 mph, while the majority of the nation could see the gusts reaching 60 mph, with potential disruptions based on the previous events. Storm Gerrit is expected to clear the #UK shores by Thursday, December 28.

Most wildfires in Atlantic Canada are human caused – whether accidental or intentional, while others are the result of weather such as lightning from thunderstorms. Regardless of how a wildfire is ignited, the weather conditions before and after a wildfire starts is crucial to how it could spread and behave. https://lnkd.in/ePGCRFRH

High pressure slowly retreats to the east towards Fennoscandia (parts of Sweden) and low pressure system with tropical and humid airmass from the southwest builds up the pressure gradient. Storm #Babet, a second named windstorm of the autumn-winter season, is expected to cross the western parts of the United Kingdom during the middle of the week, increasing the potential for very gusty and gale force winds (≥40 mph) and localised heavy rainfall across southwestern #England, #Wales / #Cymru, the #Midlands and via north across #Yorkshire and the #Humber to #Scotland, where the highest accumulations are expected (on the Scottish hills) due to the orographic ascent and seeder-feeder mechanism, i.e. a continuous lifting mechanism and system renewal. Considering drenched soils from the recent deluge, there is a high chance of significant flooding across the northern part of the country.

Wildfires Have Erased Two Decades’ Worth of Air Quality Gains in U.S., Study Finds In recent years, many people have learned first-hand how destructive wildfires can be. Even if they weren’t forced to evacuate their homes, millions in Canada and the United States have had to breathe acrid air polluted with wildfire smoke. A new study has found that an increase in the severity and frequency of wildfires in […] The post Wildfires Have Erased Two Decades’ Worth of Air Quality Gains in U.S., Study Finds appeared first on EcoWatch .

Smoke continues to impact regional air quality as Canada grapples with the worst wildfire season on record. In the northeast alone, there are currently more than 50 wildfires burning in Ontario and five active fires in Quebec https://lnkd.in/gU2wdq6e

Optimal Conditions For Forest Fire ''The dangerous 30/30/30 situation''. That's 30% humidity, 30km breezes and over 30C, which is what usually triggers these fires.

In the past 2 years, we have seen the increasing trend of a handful of flashier, more intense storms delivering a higher percentage of our yearly rainfall. Among the detrimental effects of this changing weather pattern is increased fire danger from vegetative growth that dries up and becomes fuel for dry-season fires
