Instead of listening to what youtubies have to say about the weather look at a real weather site.
The low pressure area there is currently called Invest95. Its far too weak to be a named storm. And the computer models are showing it going the opposite way that dutch is projecting.
As for the storms over Florida, its not that bad at all.
This is very typical for the summers. Inland clouds form in the heat of the day. In the afternoon, like right now, they let loose with the rain. No mystery there.
I've lived in Florida my whole life. I've been through several Hurricanes including Andrew. Even those who have access to supercomputers for projecting and have done so for decades can't always get it right. But they will come very close almost every time. Watch for the low to do the exact opposite of what Dutch says.
Then go to his youtube channel and give him a link to weather underground. Tell him to go fetch his credibility as a weather man because he has thrown it away.
