the thunder woke me up
Wild weather batters Metro Vancouver
METRO VANCOUVER - Hundreds of Metro Vancouver homes were without power Tuesday morning after a massive thunderstorm struck the region.
Many residents were shaken awake at about 5 a.m. Tuesday by rumbling thunder and bright lightning, caused by an unstable air mass hovering over Metro Vancouver.
"It was quite the light show over Surrey," Environment Canada meteorologist Lisa Coldwells said. The weather led to downed power lines in Maple Ridge and Coquitlam, where 593 homes were left without power by 8 a.m. Tuesday.
BC Hydro spokeswoman Simi Heer said extra crews had been brought in and the power was expected to be restored to all customers by Tuesday night. By 3 p.m. Tuesday, only 189 homes were without power.
The lightning was followed by a series of smaller strikes and showers throughout the region, along with heavy downpours in area such as Maple Ridge and Surrey.
"That's the nature of these storms; there's lots of overturning in the atmosphere," Coldwells said. "Once they get going they can produce heavy showers."
In Maple Ridge, 43.8 millimetres of rain fell overnight - with 19 mm falling during the height of the storm between 7 a.m. and 8 a.m. About 15 mm of rain fell in Surrey during that same hour.
Coldwells said the lightning was triggered when a cold front mixed with warm air from last weekend and moisture from Monday's showers.
The first lightning struck at about 5 a.m., she said, while the thunder "rumbled through the morning rush, waking people up."
This was followed by a smattering of lighting strikes.
Metro Vancouver usually averages about six or seven thunderstorms days a year, Coldwells said.
The region was already hit with one thunder, lightning and hailstorm this year, on March 27. More lightning was predicted for Tuesday night but was expected to be over the easter Fraser Valley, Coldwells said.
"There is a risk. All we need is sunshine to begin to stir up the moisture again," she said.
The weather office is predicting cloudy with sunny periods for today and Thursday, with sun for both Friday and Saturday and highs of 21 C and 24 C respectively.
Coldwells warns this weekend likely won't be a "repeat of last weekend" as the ridge of high pressure that brings sunny weather is hovering more over the north, and not on the coast.
