Hurricane Harvey continues to rapidly deepen and intensify. As of the 5 AM advisory, maximum sustained winds are 105 mph with gusts as high as 125 mph. However, even since that advisory, the pressure has fallen further, meaning the winds are still increasing. I expect it to be a Category 3 hurricane with 125 mph sustained winds with gusts as high as 140 mph at landfall just south of Corpus Christi, Texas around midnight tonight. However, the storm will then stall not far inland, so it will continue to dump huge amounts of rain along with strong gusty winds for days. According to the Euro model, it may emerge back over the Gulf of Mexico on Monday night and re-intensify to a Category 2 hurricane and make a 2nd landfall near the Texas/Louisiana border Wednesday night. Needless to say, catastrophic flooding will take place with rainfall amounts as high as 35 inches being within the realm of possibility.
The 2nd storm, which will be forming off the coast of Florida has trended closer to Long Island. The Canadian model still stands alone in bringing up to eastern Long Island. However, the GFS and the Euro models have both trended the storm closer to Long Island, so it bears watching the model runs.
The following image from the GFS model shows widespread rainfall amounts of 10 to 30 inches for SE Texas and SW Louisiana:
