Once again BC is the center of attention as is usually the case this time of year...
BC storm parade: A lot of rain and wind this week for the west coast. A series of storms will slam the coast bringing heavy rains and strong winds with heavy mountain snow; great for skiers! Of course this isn't anything unusual, it's that time of year where it just rains and rains. The first storm is already bringing rain, snow and winds to BC. The second one, which will be stronger than the first, will come ashore on wednesday morning. A third one is still developping and is expected to reach the coast later this week. Figure 1 shows a satellite image of the northeastern Pacific and I have marked the storms centers with a small red square. The systems don't just decipate once they reach BC, obviously, they travel across the country bringing unsettled weather with it. Once these storms cross the rockies, however, they lose much of their power... This Pattern also brings mild weather across the whole country as shown in Figure 2 with the CMC 10-day mean temperature forecast. If you look at my last update, more models are shown. Only exception to that is BC because of the constant cloud cover due to storms.
