Now I haven't been to the DR yet (well in 3 days I won't be able to say that anymore!!!) BUT have been told and read that up to the end of Nov is 'hurricane' season - however as you may already know 'Michelle' was the closest threat and 'she' is now not considered any threat to the DR.
What I've read is that currently it's raining but HOT HOT - and the rain that they do get is brief. Much better than the months of rain we get on the West (Wet?) Coast of Cda.
