 Strong winds are expected after 2 p.m., so hikers must go to the ridge before 2 p.m.

 It is safer to return before reaching the high ridge because very windy weather is coming later.

 You should turn back because the ridge is closed for repairs this afternoon.

 Because of thunderstorms, the trail is open only in the areas with thunder.

 If you hear thunder, you can stay in open areas as long as you go down later.

 If there is thunder, you should move away from exposed places and descend straight away.

 Heavy rain forecast means you must cross the river quickly before it starts rising.

 The river crossing is unsafe, so it is closed all day even if the water stays low.

 You should avoid crossing the river when the water level is going up because it could be dangerous.

 You should stay near the summit, even if you cannot see the marked path clearly.

 Because it may be hard to see, you have to keep to the official trail and avoid other routes.

 Low visibility means you must look for the summit markers by following unmarked tracks.

 You should use footwear that won’t slip and be especially careful on steep parts because there may be ice.

 Ice is possible on shaded sections, so shaded sections are the only places you should walk.

 You must wear new boots, or you are not allowed to use the trail today.
