Why?

I don't know. Look at the link, and it shows the criteria across Canada. For some reason they think it will never get hot enough in Victoria or Kelowna to issue a heat warning.

Thanks. The link wasn't working for me earlier.

Southern portions of Metro Vancouver and the Western Fraser Valley can expect to see lesser rainfall amounts.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Snowfall warning in effect for:

Metro Vancouver
Snowfall amounts of 10 to 20 cm are expected by Saturday morning.

A weak warm front is expected to move north from Washington State on Friday morning bringing bands of light snow to the Lower Mainland and Southern Vancouver Island on Friday. The warm front will be followed closely by a low pressure system which will bring heavier snow to the area beginning Friday evening. Total snowfall amounts of 10 to 20 cm are expected by early Saturday morning. On Friday night the snow may become mixed with or change to rain at lower elevations especially near the Strait of Georgia. Freezing rain is also a possibility in the Fraser Valley on Friday night.

Be prepared to adjust your driving with changing road conditions. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

5:36 AM PST Saturday 04 February 2017
Snowfall warning in effect for:

Fraser Valley - east including Chilliwack
Fraser Valley - west including Abbotsford
A long period of snowfall, with total amounts of 10 to 20 cm is expected.

A low pressure centre off the west coast of Vancouver Island is causing moist maritime air to overrun cold arctic air in the low levels, causing areas of heavy snowfall over the Inner South Coast.

The highest amounts are forecast for the Fraser Valley where up to 20 cm of further snowfall is likely through Sunday morning. 20 cm of snow had already fallen at Abbotsford Airport as of 4 AM this morning.

A few more centimetres of snow are forecast for the remainder of the regions mainly this morning and again tonight, with accumulations of around 2 to 4 cm today and again tonight, with lesser amounts near the Strait of Georgia and higher amounts inland and over higher terrain.

Be prepared to adjust your driving with changing road conditions. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

Winter storm warning in effect for:

Metro Vancouver
Hazardous winter conditions are expected.

An intense Pacific warm front will arrive late Wednesday afternoon. The front will move in from the south and spread warmer, moist air over the colder Arctic air still in place at the surface.

Snow will start falling Wednesday afternoon and become heavier into the evening. As the warm air establishes itself, there will be a good chance of freezing rain followed by significant rainfall overnight Wednesday and Thursday.

The transition to rain is expected earliest along the immediate coast. Further inland, snow will persist longer and the risk of freezing rain will increase. As a result, snowfall amounts will vary considerably across the region, from 5 cm near the coast to possibly more than 15 cm.

Rapidly accumulating snow could make travel difficult over some locations. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Localized flooding in low-lying areas is possible.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ec.tempetepacifique-pacificstorm.ec@canada.ca or tweet reports to #BCStorm.

Winter storm warning in effect for:

Fraser Valley - east including Chilliwack
Fraser Valley - west including Abbotsford
Hazardous winter conditions are expected.

An intense Pacific warm front will arrive late Wednesday afternoon. The front will move in from the south and spread warmer, moist air over the colder Arctic air still in place at the surface.

Snow will start falling Wednesday afternoon and become heavy in the evening. Blowing snow will further reduce visibilities in some areas. As the warm air establishes itself, the snow will change to freezing rain starting over western sections. The freezing rain will then migrate slowly eastward Wednesday night. There is the potential for an extended period of freezing rain before the eventual transition to rain.

Snowfall amounts will vary from around 5 cm near the US border to 20 cm or more near Hope where snow may persist through the night.

Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Consider postponing non-essential travel until conditions improve.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ec.tempetepacifique-pacificstorm.ec@canada.ca or tweet reports to #BCStorm.

In the Fraser Canyon the amounts will range from 15 to 20 cm near Lytton to 50 cm near Boston Bar. Freezing rain is also expected near Hope on Thursday.

What does it take to get a snowfall warning? Well that really depends on where you live.
