Download Flash Player to view this content.
- After a nice start to the day for many, a few showers are still on tap to brush the south coast this afternoon
- However today is generally a dry day as we sit behind yesterday's system, and ahead of the atmospheric river
- Rainfall warnings are already in place for western Vancouver Island for 100-120 mm and in Howe Sound for 50-70 mm through Saturday. Special weather statement for the rest of the south coast
- Rain will likely begin after the midnight hour tonight as a Pacific frontal system opens the door to a stream of moisture coming straight from the sub-tropical Hawaiian Islands
- Heavy rain will continue for Vancouver through Saturday before tapering down Sunday afternoon. Rainfall totals during this time period for Vancouver could be +50 mm
- High snow levels and locally windy conditions will also accompany the heavy rain
- By Sunday afternoon the plume of moisture will sink south and we -may- even get to end the soggy weekend off with some late Sunday sunshine (which of course will be out an hour longer)
- The threat for avalanches is high right across southern BC this weekend. In fact several interior highways are closed today due to avalaches: http://www.drivebc.ca/#
The atmospheric river starts up early tomorrow morning for heavy rain through to Sunday afternoon for the south coast
2011 Oklahoma Induced Earthquake May Have Triggered Larger Quake
- A new study released today from the USGS observed that a human-induced magnitude 5.0 earthquake near Prague, Oklahoma in November 2011 may have triggered the larger M5.7 earthquake less than a day later.
- This research suggests that the M5.7 quake was the largest human-caused earthquake associated with wastewater injection.

Prairies 30 DEGREE Warm-up This Weekend
- Know we touched on this last night but last weekend the Prairies were in dangerous cold wind chills: -40 values and colder overnight, approaching -60 in Regina
- This weekend, that same system that brought the snow and rough driving conditions yesterday is helping to usher in mild air for +3-5 degrees this weekend, and into the teens in southern Alberta thanks to Chinook winds.
- With seasonal temps from ON through to the Maritimes as well, NFLD will be the only ones not exactly feeling Spring-like this weekend with a 10 cm snowstorm on route to St. John's tomorrow night

The Great Lakes Now have most March ice in 41 years of records
- Although temperatures are thankfully above zero for the next few days across the lower Great Lakes, the Great Lakes ice cover continued its historic expansion up until yesterday- covering more than 92 percent of the water's surface, the most on record in March and so late in the winter. (It was just over 91%, most in 35 years a few days ago)

California could be in for century-long Megadrought
- Although the announcement from NOAA yesterday of a 50% of El Nino returning this summer, meant hope for California rains, some scientists are warning of a 'mega drought' for the state that is 95% under drought conditions already
- A team of scientists used sediment cores to study the history of drought in the West back about 3,000 years and found California is in one of its driest periods since 1580.
- Also, while a 3-5 year drought is often thought of as being a long drought, history shows they can last over a decade, and in some cases, they can last over a century
