LAMM 2009 - WEATHER FORECAST
By David Braine - BBC Weather

A CHALLENGING WEATHER FORECAST
Please bring a selection of heavier garments to the event so that you can choose appropriate clothing/tent before you start. Please don't make the same mistakes as in 2004 and come to the LAMM with only Summer equipment. This present heat wave could so easily lull all of us into a false sense of security and make us forget how serious the Scottish Mountains can be, even in Summer.
