What's Left of Fay Could Bring Us Rain... and Gustav Enters the Picture!

The remnants of Tropical Storm Fay will be inching northeast toward the Mid-Atlantic over the next 24-48 hours. There is some disagreement in how much rain we may get, as the popular GFS/ECMWF models show a good slug of rain entering the region by Wednesday, with the threat of precipitation continuing through Friday. Meanwhile the NAM model shows the axis of significant moisture remaining west, with a drier scenario. At this point, with an increasing onshore flow, I have to believe our rain chances will increase on Wednesday and we may receive some decent rainfall on Thursday, lingering into Friday what's left of the system crosses the region. Stay tuned for more...

The newest storm on the horizon is Tropical Storm Gustav. Gustav is located south-southeast of Haiti and moving northwest at about 14 mph as of late afternoon/early evening. The forward speed is expected to decrease over the next couple of days, with the center likely moving over Haiti tomorrow. With strenghtening expected, Gustav could become a hurricane prior to moving over land. In the longer term, it is forecast to move over Cuba and potentially end up in the Gulf of Mexico. Below, you can see the official track forecast from the National Hurricane Center, along with the computer model projections from their afternoon runs.
