Posts from Trip Advisor have been invaluable in planning our trip to PR and I'm hoping to benefit from you all again! I know it's the tropics and rain can come out of nowhere and head out as quickly but the forecast for this weekend coupled with the flash flood warning has me a little concerned. We are flying into SJU tomorrow and staying in Old San Juan tomorrow night. Are the areas between the airport and Old San Juan a place that has flooding issues? Also we are driving down to Copamarina on Saturday - does anyone know how that highway is during heavy rains? Does it ever have flooding issues? Thanks so much for any info - I'm sure we'll still have a great time, just trying to get a better idea of what we're heading into!
