too bad it's not snow...

As l've aged over the years like fine wine Ms. I'mrunningoutofnamescreeks. Snow is just in our imaginations it seems it's related to we know it's somewhere out there.

Interesting info. I've never seen or heard of it before. Looking forward to learning more.

Yes growing up in Vancouver you get accustomed to seeing the same mountains day after day but since moving further east you get to see more of the coastal mountains.
And some are rather unique in both appearance and elevation of course trips through B.C. is also another source of interest in mountains l've always had a fascination with our awesome scenery in B.C. you can never tire of it.
There's one mountain out Chilliwack way that looks like a glacier don't know the name l'll get a picture on a clear day.
I haven't found out the name but it reminds me of Forbidden plateau behind Courtney similar look.

B.C. flood risk elevated, conditions not seen in a decade
June 9, 2022
https://vancouver.citynews.ca/2022/06/0 ... onditions/

There’s an increased risk of flood in B.C. right now, and experts say the cooler weather is a big factor. The next few weeks will be a critical window of time to see what comes next.

Dave Campbell with the River Forecast Centre says the snowmelt is about three to four weeks later than usual because of the cooler temperatures. Usually, about half the pack has melted by now, but so far this year, only 20 per cent has.

The forecast is stable, with rain and heat for the weeks ahead. However, the conditions have the potential to not be so stable.

“We certainly have elevated risk around the province this year. We’re seeing the high snowpack. The snow levels we have are unusually high, probably something that we see once every decade or so. The last time we had similar conditions was back in 2012,” Campbell said.

The late snowmelt means should temperatures spike and/or we see substantial rain, the rivers could flood. However, unlike the atmospheric river last fall that overflowed rivers in a matter of days, this is expected to be a slower increase in water levels, allowing for more time to react.

“There’s nothing imminent that we’re seeing in terms of things like the Fraser River, but we know that the next few weeks is going to be that critical window of time,” Campbell said.

In the Terrace area, the flood risk has already led to 300 evacuations.

Emergency Management BC is urging people living in flood risk areas, such as the Fraser River, to have go-bags ready and keep a close eye on conditions. The go-bags should include essentials such as medications and copies of important documents.

People in high-risk areas should also reach out to family and friends to make arrangements, in the event they need to leave their homes.

“British Columbians should pay close attention to weather forecasts and their local authorities, and focus on the weather alerts from your area from Environment Canada,” said Pader Brach with Emergency Management BC. “Listen to your First Nation or local government, especially if evacuation alerts or evacuation orders are issued.”

The agency says it is “pre-positioning flood mitigation assets” across the province.

“This includes sandbags and sandbag machines, tiger dams, and gabions,” Brach explained.

“If you’re in an area of elevated risk, you can help prevent flooding by making sure gutters in the storm drains on your street are clear of leaves and debris. Keep away from river edges and shorelines during periods of high flow. Riverbanks may be unstable and more prone to collapse.”

If you come across flooding on the road, be careful and do not try to drive through floodwater.

“The depth of water pooling on the roads is not always obvious and can be dangerous,” Brach warned.

There's that 2012 mention again. Despite the lack of extreme heat, it would be nice to see a repeat of that summer into early fall simply due to the prolonged dry spell.

High streamflow advisory issued for B.C.'s Lower Fraser River
June 8, 2022
https://www.cbc.ca/news/canada/british- ... -1.6482348

A high streamflow advisory has been issued for several British Columbia communities along the Lower Fraser River due to increasing snowmelt and wet weather.

The River Forecast Centre says the advisory applies to areas from Quesnel downstream, including Big Bar, Boston Bar and the Fraser Valley from Hope to the ocean.

It says water flow in the Fraser River's tributaries is expected to make its way to the Lower Fraser at Hope and downstream through the weekend, while rain Thursday is expected to increase river flow which may remain high over the next few weeks or even longer.

Flood watches and warnings around B.C.
The advisory is the latest addition to a series of flood watches and warnings issued by the centre for rivers and their tributaries around the province.

A survey from June 1 released by the Ministry of Forests showing data from more than 100 weather stations indicates snow levels are well above normal, an increase from the assessment done in mid-May.

The report says flood risk remains high because of delayed snowmelt, and as of June 1, there was an average snowpack of 165 per cent above normal, up from 128 per cent of normal during the survey done on May 15.

"All regions of the province with snow measurements have snow basin indices greater than 140 per cent of normal, indicating significant risk throughout the B.C. Interior from snowmelt related flooding,'' the report says.

Six stations measured record-high snow, including sites in the Upper Fraser east, Quesnel, North Thompson, South Thompson and Upper Columbia, highlighting areas that are still at increased risk for flooding, the report says.

The report says normally about half the snowpack is melted by June 1, but cooler weather has delayed that by two to four weeks and just 19 per cent of the snowpack at the automated weather stations had melted.

The Stikine-area snowpack in northwest B.C. is 289 per cent of normal, the same area where a flood warning has been posted for the Liard River, flood watches are up for the Skeena and Bulkley rivers, and high streamflow advisories cover the Stikine and Swift rivers.

The areas affect the communities of Fort Nelson, Watson Lake, Telkwa, Smithers, Hazelton, Kispiox, Terrace, Dease Lake and Telegraph Creek.

Communities vulnerable over next few weeks
The River Forecast Centre says that the Lower Fraser River will remain vulnerable to extreme weather events, especially heavy rainfall or extreme heat over the next few weeks.

However, it says that while forecasts are not indicating extreme heat, unsettled weather with rain in the Interior is anticipated to continue.

"The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high streamflow period,'' says the advisory.

The B.C. government is telling residents of flood-prone areas to be prepared for flooding, advising people to store valuable and important documents in watertight containers or on a tall shelf or upper floor.

It's also asking people to understand that while no major flooding is expected, as rivers start to rise, minor flooding in low-lying areas is possible.

The high streamflow advisory is the lowest of the three levels issued by the River Forecast Centre.

A flood watch follows an advisory and indicates river levels may exceed the bank, and flooding could occur.

A flood warning suggests an evacuation alert may be issued, followed by an evacuation order, meaning people must immediately leave their property.

Flood advisory in place for Langley Township as Fraser River water level rises
June 9, 2022
https://www.aldergrovestar.com/news/flo ... vel-rises/

Langley Township is increasing its surveillance of local dikes as the level of the Fraser River has begun rising rapidly, with a lot of snow still left to melt in the mountains of the Interior.

A high streamflow advisory was issued for the Lower Fraser River by the province on Thursday.

“It’s just starting to come up,” said Aaron Ruhl, the manager of engineering operations for the Township.

On Thursday, June 9, the Fraser River reached five meters at the Mission Gauge, the main gauge used for this stretch of the river.

At that level, the Township starts weekly dike inspections. At 5.5 meters – which is expected to happen as early as this weekend, June 11-12 – that goes to daily inspections. Trails at the boat launch in Fort Langley are likely to be closed down as they become flooded in low-lying areas, and parts of Glen Valley, particularly some fields, will see some localized flooding.

There are already a few local closures on the river, as Metro Vancouver has closed off parts of Brae Island’s trail networks, and overnight camping has been suspended at Edgewater Bar in Derby Reach Regional Park.

Provincially, WorkSafe BC was among the agencies advising for increased preparedness.

“The most important thing that an employer can do is be prepared,” said Al Johnson, head of prevention services at WorkSafeBC. “With the elevated risk of flooding across the province, it is essential that employers do a risk assessment and have an emergency response plan that includes flood risks.”

There is also a flood advisory in effect as of Thursday in the Township, Ruhl said.

However, the Township and the Fraser Valley in general has seen river levels hit this height several times in recent years.

In 2012, the river reached a peak of 6.37 meters at the Mission Gauge. That caused some roads near the river to be flooded out, many fields were waterlogged, and there were even fears that derelict boats docked near Mission could have been torn loose from their moorings.

A few properties in Glen Valley were pre-emptively evacuated, but fortunately the waters receded without doing major damage.

In that year, and in several since then, there have also been efforts to sandbag vulnerable homes and buildings near the river, including at the Katzie and Kwantlen First Nation reserves in Langley.

Ruhl noted that sand and sandbags are available for free to locals at the Langley Township Operations Centre, at 4700 224 St.

The Township is also meeting with other levels of government, and if the waters keep rising, will open an Emergency Operations Centre.

There are fears that possible flooding could hit sometime this June because of the extremely cool and damp spring, which deposited large snowpacks late in the season on parts of the Interior. That snow is now finally melting, and pouring into the Fraser River and its tributaries.

High streamflow advisory issued for B.C. rivers overwhelmed by November's floods

Central B.C. snowmelt to send 'pulse of water' downstream toward Fraser River

A high streamflow advisory has been issued by the River Forecast Centre for some of the same British Columbia rivers where flooding last November ripped away roads and devastated communities.

The centre says snowmelt above the North Thompson River in central B.C. will send a "pulse" of water downstream toward the Fraser River.

It says while the water level is expected to rise, no significant rain or heat is in the forecast that would produce major increases in flow through the river.

Rain from last week is still moving through reservoirs, prompting a high streamflow advisory for the Nicola River, the same river that was flooded last November, washing away large sections of Highway 8 and stranding communities.

The centre says that although long-term water monitoring sites were destroyed on the river during last November's historic flooding, it is likely that the pulse of water will increase flows downstream.

However, significant rainfall is not currently forecast for the region.

The centre is advising the public to stay clear of fast-moving rivers and potentially unstable riverbanks during the high-streamflow period.

A provincial state of emergency was declared last fall after storms washed away highways and flooded communities in the Interior and the Fraser Valley.

Seriously, after a decent day , more downpours this evening? This is getting comical , funnier than a barrel of sardines . Predicting daily rain is easy, like shooting fish in a barrel. Roll out the barrel , we'll have a barrel of fun.

We miss your monthly stats pal, you haven't posted one since winter.

Sorry for the delay. I'll post them soon.

Well, as long as you're not shooting sardines in a barrel, that'll put a hole in it and more water on the ground.

I did notice that having a rare dry day is so much more of a treat, almost as good as and as rare
