Parade of cyclones incoming to BC:
A “parade of cyclones” directed towards southwest British Columbia could worsen flooding and mudslide situations within the week, according to the meteorologist liable for alerting preparation at Environment and Climate Change Canada.
Armel Castellan declared the first storm system, anticipated to come Thursday, won’t bring rains as large as those that triggered public loss last week.
However, the rain will be significant just to “exacerbate the vulnerabilities on the ground currently,” he declared.
“With the Thursday system, it is an atmospheric river, tapping into some subtropical moisture and heat. It’s going to bring freezing levels [on mountains] up to 2,500 metres, so fairly high — there will be some snowmelt with this moisture,” he stated. Source – cbc.ca
Castellan foretells 40 to 70 millimetres falling in the flood-submerged Fraser Valley, and upwards of 100 millimetres on the North Shore peaks and Howe Sound.
After that regularity is drawn out, another atmospheric river is anticipated to follow in quick order, tapping Saturday afternoon.
Castellan told with some regions already at 200 per cent of the average seasonal rainfall, the concern is the incoming rain will be falling on the area that is already soaked. On hillsides, that means a higher possibility of water flowing downhill and generating mudslides and valley flooding.
“I would just caution that we are dealing with very active weather for the foreseeable future,” he stated. Source – cbc.ca
A set of warnings and special climate records are also in impact for the northern half of the region, originally for severely powerful winds and snowfall.
