Parts of Canada and the USA are facing severe heat waves and the police department of British Columbia province of Canada has received calls of more than 300+ sudden deaths, most of them were older people, due to extreme heat conditions. Just 3 hours north-east of Vancouver in a small city Lytton the temperature soared to 49.5° C, thus making it the hottest place on earth at that time. Because of extreme prevailing heat conditions, flood warnings have been issued downstream of Lytton as sudden snow and ice melt has created a torrent of rushing water. For the time being, Canada’s glaciers are melting so fast they’re flooding out homes in residential areas.
More than 2 cooling centres have been set up in Vancouver where air conditioning is being provided as most houses in British Columbia don’t have cooling facilities. Many people living in south-facing apartments are even forced to leave their homes and rent hotel rooms.
The heatwave has also grasped the US’s North-western states Washington and Oregon. More than 60 death have been recorded in Oregon alone.
Scientists claim this is because of a weather phenomenon called heat dome- a mountain of warm air pressing down across a huge area and refusing to move. As warm air tries to rise, this high-pressure system above pushes the warm air back down to the surface. It becomes denser and hotter as it gets compressed.
The heat dome is now moving eastwards over Canada’s Alberta and Saskatchewan and parts of Manitoba have been placed under heat warnings. Weather forecasters expect the heat to ease near US western coastal regions, and in Seattle and Portland, but is expected to last all week in the interior areas of the Pacific Northwest.
