They also don't really decide what to do until it's closer to shore. A 20 mile shift means EVERYTHING.

And people who live up north don't get that at all.

When I lived in Central Florida, NHC and Central Florida Hurricane Center were my go to spots for info.

This can be dangerous for the area she's fixing to make landfall. Will be very hot and humid in the immediate aftermath, and also very loud with the generators running. Not to mention this time will be different because of covid 19 being in the mix.

The flooding will be the worst thing, you should evacuate if your house is along any water ways. Sometimes the waters get so high you have to climb into your attic and have no where else to go and the water still keeps rising.

wow 150...well it continues to intrigue me how the models are so amazing at hurricane tracking,path and size...but clueless on intensity more than a day out. Blew Marco one way and blew Laura the other way. Yet had the path and speed dead on.

Hurricane Laura's maximum winds have increased by 65 mph in 24 hours (from 75 mph to 140 mph). That's the fastest 24-hr wind intensification for an Atlantic tropical cyclone since Hurricane Maria in 2017.

Google's got it making landfall just after 12 Central time near Holly Beach by the Texas border, and high tide will be at 12:30 ish, prediction of 15 ft wave heights just after 1... the forecaster was right, Cameron Parish will become part of the ocean at times tonight...

i'm not a meterologist (and don't pretend to be one) but it is truly crazy to see how organized Laura is... its such a well-rounded storm with a well-constructed eye wall... especially considering that 24 hours ago this storm was a Cat1/Cat2 storm...
