Should I be concerned about this?

We land in Jamaica on Monday, June 18th. This website says "potential for flooding rains". Also, there is at least a 60% chance of rain every day through June 22 which is the farthest the forecast goes... Thoughts?

What is there to do at CN if it's raining all day?
