When I lived in Florida, one learned to watch the Gulf very carefully. I was a regular reader of Jeff Masters at the weather underground. I can still remember his writing on Katrina.
Part of lving in Florida is learning to learn about the forecasts and the models. The two best are the Euro and the GFS.
So consider below 60 inches of rain. It is unimaginable. Cataclysmic.
Let me translate this: the most reliable hurricane model is projecting 60 inches of rain for Texas – an unimaginable number. https:/t.co/VGFep0vv40

I always recomment following Jeff Masters, who is here.
He cites another piece that is worth reading. Pro-publica did a piece on the effect of a hurricane hitting Houston. This isn’t likely to be a direct hit on Houston, but the size of the hurricane and the amount of rain may make some of what is described possible.
