JASPER, Alta. - Rain has helped to slow a fire that forced the evacuation of 1,000 tourists and outdoor enthusiasts from the popular Maligne Valley in Alberta's Jasper National Park.

Parks Canada spokeswoman Kim Weir says between four and six millimetres fell overnight and more rain is in the forecast.

She says the 50-square-kilometre blaze hasn't grown and isn't expected to if weather conditions hold.

Weir says crews are now able to get on the ground and attack the flames directly.

Lightning is believed to have sparked the fire on Thursday.

Weir says no facilities are threatened by the fire and the Jasper townsite is safe.
