If you have outdoor sightseeing schedules, tourists should arrange them in favorable weather times, and limit long journeys until late afternoon when the possibility of thunderstorms may increase.
3. Prepare necessary items
Raincoats, umbrellas and good-grip shoes are items to prepare when traveling in weather conditions where rain is likely to occur. Visitors should also bring waterproof bags to protect their phones, papers and personal belongings.
4. Slow down when it rains
For tourists traveling by motorbike, it is necessary to actively reduce speed when rain appears, especially on mountain passes, slopes and many curves. When visibility is limited or the road surface is slippery, you should find a suitable location to stop and rest.
5. Temporarily stop the journey when there is thunderstorm
If thunder, strong winds or heavy rain appear, visitors should not try to continue moving outdoors. Find a solid, safe shelter and wait for the weather to stabilize before continuing the journey.
6. Avoid sheltering under trees and unsafe areas
When there is a thunderstorm, do not stand under large trees, near power poles, billboards or temporary structures. Wind gusts, lightning and broken branches can be dangerous.
7. Flexible schedule changes
If the area expected to be visited shows warnings of heavy rain, thunderstorms or risk of landslides, tourists should consider changing their itinerary, prioritizing safe destinations and avoiding moving through areas with unfavorable weather.
