 You should stay back from cliffs because high winds are likely later today, and drones are not permitted.

 You should visit the cliffs this afternoon because the wind will be calmer and safer then.

 Strong winds are expected this afternoon, so you must fly drones near the cliff edges.

 You can shelter under a tree if you hear thunder because it is safer than a car.

 When thunder starts, you must move away from open places at once and find safe cover in a car or building.

 Thunderstorm risk today, so you should stay in open areas until the thunder stops.

 You should avoid shade at midday so you can finish your walk faster in the heat.

 Heat alert: carry 2 litres of water, so you must drink only 2 litres all day.

 You should bring plenty of water, begin hiking in the morning, and take a break in the shade around midday.

 The trails may flood quickly, so the park will close all paths for the whole week.

 Because flooding can happen suddenly, you must avoid crossing rivers when the current is strong.

 Heavy rain forecast, so you should enter river crossings when water is moving fast.

 Because it is hard to see, you should follow the marked trail and hike with someone else.

 Visibility is low, so you must walk alone to avoid disturbing other visitors.

 Fog on the summit this morning, so you can leave the marked paths to find a better view.
