Just follow the local tv stations weather reporting.
Www.wesh.com (NBC).
Www.local6.com (CBS) or
www.wftv.com (Abc). All will keep you in the loop weather wise. I've Lived in Central Florida for 62 years and I watch the weather on these stations before heading to WDW. I know last year they closed areas of WDW for Hurricane Matthew in October, but I don't remember anything in August or September last year that caused much weather worry & I have an outdoor business so I would have been ready to batten everything down. Right now we are getting our every afternoon rainstorms lasting for at least 1/2 hour. Where I live it rained for almost 2 hours tonight though.
