Typical Summer weather for central Florida, is for an afternoon/evening thunderstorms to pop up. They last about an hour or so (normally).
Dump a lot of rain and move on or dissipate.
Often the percentage given on the weather forecast (30%, 40%) is coverage rather than a chance of water falling from the sky.
Its going to rain, but on 30% of us. The storms move around differently from day to day depending on the sea breezes. You can look at a dark sky on the horizon and never feel a drop of rain, or you could be getting wet in 10 minutes.
Put a radar app on your phone, keep an eye on the clouds and bring a poncho or two. (extra shoes and socks or quick drying shoes are good too)
The rain helps cool things down a bit, but will make it very steamy.
We do occasionally get a more rainy week (this coming week looks to be that). In this case, its because of extra tropical weather that has come our way. Today we have a tropical storm dumping extra wet on us.
Welcome to Sunny Florida!
