It's snowed a bit over night so conditions improved on yesterday. But it's very foggy. You can't see 10 years ahead so hopefully there's no nasty accidents because of it!For those arriving today it's good news. And the temp is -1C at the mo. so getting colder again which is desperately needed.
Ps- Kas has caught Bobbys man flu so she may not get chance to update today so thought I would.
Have fun.
re: Boro Sat 29th Dwc
Thanks Paul. Does that mean the snow cannons should be up and running then?Feel a bit better after reading that.
Have been worrying that by we get there we'll be greeted by scenes looking like The Sound of Music!
re: Boro Sat 29th Dwc
Hi to all in Borovets.The extra snow is wecome, however the temp needs to be -4 for them to run the cannons. That is why they are not working now.
Get well soon Kas, two excited boys and there parents leaving East Mids this afternoon, Boro bound. !!TJMXU
re: Boro Sat 29th Dwc
Minus 4?? I was told they work at plus 2! That was in France Austria etc though. I have seen them on at plus 5 in some countries. Maybe they are behind the times in Bulgaria. Apparently the temperatures will be below that at night for the next week anyway so they should be on then, hopefully.

Some info about snow making from another site -
Standard thermometers measure the dry bulb temperature of the atmosphere; but the most important factor for snow conditions is the wet bulb temperature.
The wet bulb temperature is a function of the dry bulb temperature and the relative humidity, the amount of water vapor in the air. Liquid or solid water cools itself by evaporating some water as water vapor. This releases heat, and so lowers the energy level in the water. When there is ...

The wet bulb temperature is a function of the dry bulb temperature and the relative humidity, the amount of water vapor in the air. Liquid or solid water cools itself by evaporating some water as water vapor. This releases heat, and so lowers the energy level in the water. When there is more water vapor in the atmosphere, water or snow can't evaporate as much because the air is already saturated with water to a high degree. Consequently, water cools more slowly when the humidity is high, and more quickly when the humidity is low.
For this reason, humidity is a very important factor in determining snow conditions. If the humidity level is low enough, you can actually get snow even when the dry bulb temperature is several degrees above freezing. If the relative humidity is 100 percent, then the wet bulb temperature and the dry bulb temperature will be exactly the same. But even if both are at the freezing temperature, you might get rain instead of snow because the air saturation slows the cooling process down so much.
If the temperature is around 30 F (-1 C), you need a fairly low relative humidity (less than 30 percent) for good snow-making conditions. If the temperature is less than 20 F (-6.7 C), you can make snow fairly easily even if the relative humidity is 100 percent. A temperature in the teens is ideal for snow-making.

re: Boro Sat 29th Dwc
very interesting but the canons in Borovets still need temps of -4 or lower to operate no matter what the humidity isre: Boro Sat 29th Dwc
I wonder how they manage in these Chill Factor places, in England?! It is a shame that the cannons at Boro aren't as sophisticated as those ones.
How are snow conds today then?
And the weather maps are showing low temps through the week next week.

Maybe it's just me... But when the temperature is above freezing then the only result of having snow cannons on would be liquid snow as Kas/Bobby call it. I.e. rain?!?
Certainly at the indoor snow place near me the snow is 'made' at a toasty -2 to -3 degrees. I'm not sure anywhere would waste their time or money making snow at +5 degrees. It would surely just melt?!? Even if it were possible?
If this is simply a wind up and I've been the clown that has taken the first 'bite', then "oh ...

The weather will be what it'll be. Simples. Cannons have been on loads In recent weeks in Boro. Don't panic Capt. Mannering. You WILL ski/board. Whatever takes your fancy!

Good statement Paul
re: Boro Sat 29th Dwc
Doh hit the wrong button.
Good statement Paul G.
Been going to Boro last 13 yrs snow always turns up never failed, so look out Jan 26th cause we're gonna get it.
S.P.
