If it makes you feel any better, the island really needed that rain (and the rains we are getting today and through the weekend). Prior to your arrival, a lot of the island was in Extreme drought conditions, with water use restrictions in place and a high risk of fires. Today, there is only a very small portion of the island that is in Abnormally Dry conditions and none of the island is considered to be affected by drought.
