Hello Jo, Well, I've been following your Blog and congratulations that you have all got to Astorga, considering the time of the year you decided to walk.
Try and look at
http://www.mundicamino.com (you can then choose English instead of Spanish). Go to WEATHER along the top line of the page. Then click
CAMINO FRANCES and scroll down passing all the towns along the route until you come to Astorga and places further on. From what I see, the bad weather in your area won't clear up until Tuesday! Remember to look at the ALTITUDE of the town you are interested in and then look at the icon depicting the weather over the next few days.
Looking at the Web cam with the view of O'Cebreiro just a few minutes ago, it's snowing and looks pretty deep! Obviously it would be foolish to even attempt your next stretch, say until Molinaseca until the weekend has passed. Maybe by then things will have calmed down and you could try advancing, first to Villafranca and maybe a way up the valley. At that point, if walking becomes really difficult, you could probably pick up a local bus to take you round O'Cebreiro and try to get to Triacastela and from there, you should be OK. It's a pity, because you will miss two of the most beautiful parts of the Camino, but safety must come first. We met parents of a Dutch pilgrim who died in a snowstorm this February, trying to get to Roncevalles (admitedly a higher route, but never underestimate the mountains).
In the meantime, try and find out what local bus alternatives there are, so that you can work out Plan B - or even C and D!Good luck. Anne
