Weather Notes
As the 19th-century American poet W.C. Byrant put it so adroitly in his poem To the Apennines: ‘There the winds no barrier know’. Be prepared for amazingly strong one-way winds that come howling in from the west and the Tyrrhenian coast and batter the Sibillini leaving little upright – walkers included – before heading over to the Adriatic coast. These conditions are prohibitive and to embark on ridge routes on such days is not just inadvisable but downright dangerous. A positive legacy of this nuisance is the stunning visibility and long-distance views left in its aftermath. Another meteorological phenomenon not be under-rated is mist and low cloud. This can transform even the easiest trail into a trying exercise in orienteering. What’s more, wet grass can be slippery. The Piano Grande zone is especially prone, though the upside is atmospheric photographs for those who are patient enough.
