A weakened Irma will head into southwestern Georgia today and then turn northwestward towards the Tennessee Valley region. At 8am, Irma was moving NNW at 18 mph and classified as a tropical storm with max sustained winds at 70 mph and a central pressure of 970 mb. As it arrives over the Tennessee Valley late this evening into Tuesday morning, it is expected to weaken to a tropical depression spreading 2 to 3 inches of rainfall with isolated amounts up to 4 inches across the area. Winds are also expected to be between 20 to 25 MPH with higher gusts up to 40 to 45 MPH. Due to strong high pressure ridging across the Great Lakes region, Irma’s remains will stall out in its advance to the north and gradually dissipate over the Tennessee Valley over the next few days.

Irma continues to track west-northwest as a major hurricane - now at category 4 status - and is likely to maintain much of its strength over the next couple of days as it moves over very warm waters. Irma should move to a position quite close to the southeastern coast of Florida by early Sunday and then it is likely to turn northward as deep upper-level troughing digs in over the Northeast US. This likely path will result in virtually the entire state of Florida experiencing hurricane conditions later this weekend and into early Monday as the hurricane crosses from south-to-north roughly over the center of Florida. At landfall, Irma is likely to have category 4 status, but category 5 status is not out of the realm of possibility. By the time Irma reaches the central and northern parts of Florida, it is likely to have weakened some to perhaps category 2 level.

Hurricane Irma continues on a WNW track as a category 5 “major” hurricane. The hurricane is being steered by a subtropical ridge to the north and this motion should continue for the next 48 hours or so. After that, an upper-level trough will dig into the eastern US and allow Irma to turn northward. There is still some uncertainty about the timing of this turn northward, but major impact is very likely across southern Florida over the weekend as it makes its turn.

Irma continues to grind westward over the Atlantic as a major hurricane and it is looking increasingly likely that it will impact southern Florida in a significant way by later in the weekend and central Florida can expect some impact as well. Irma is likely to approach the Florida Straits by early in the weekend and then perhaps shift its westward track to more of a northward turn and this could bring it over the western side of the state on a path from south-to-north towards the interior Southeast US.

Irma continues to churn westward over the Atlantic as a major hurricane and it is looking increasingly likely that it will impact southern Florida in a significant way by later in the weekend. Irma is likely to approach the Florida Straits by early in the weekend and then perhaps shift to a northward path which could bring it over the state of Florida on a path towards the interior Southeast US. As of the last report, Irma’s max sustained winds are near 175 mph which gives it a dangerous category 5 “major” hurricane status.

The remnants of Harvey continue to weaken and push away from the region, but the overall scene in the tropics remains quite active. Hurricane Irma is going to track generally in a westward direction over the next several days and further intensification is likely. This system will have to be monitored closely in coming days as it could be a big concern for somewhere in the US in about ten days or so.

As the remnants of Harvey continue to push through the Tennessee Valley, our chance of showers and thunderstorms will continue for another day and some of the storms that form can be on the strong side. This system will then get absorbed into a developing trough over the Northeast and pull away from around here on Friday. The tropics continue to be quite active and multiple systems may impact the Southeast US over the next couple of weeks. One big concern is Hurricane Irma over the eastern Atlantic as it could become a major player in about ten days or so. Stay tuned.

Some of the remains of Hurricane Harvey are now impacting the Tennessee Valley and the clouds and occasional rain will keep us cooler than yesterday. Some of the rain can be heavy at times later today and tonight. The circulation center of Harvey will make a second landfall near the TX/LA coastline today and then get absorbed into a northern stream trough of low pressure. A second tropical system along the Mid-Atlantic coastline will push away and out to sea during the day.

The remains of Hurricane Harvey continue to bring significant rainfall to the Deep South and a second tropical system is riding up along the east coast. This second system is likely to spread some significant rain today to southeastern Virginia and coastal Delmarva and New Jersey.

The remains of Hurricane Harvey will continue to result in torrential rainfall for parts of Texas and Louisiana with as much as 20 additional inches of rain possible in some sections over the next few days. Last week’s greatest fears of upwards of 3 or 4 feet of rain is coming to fruition in some parts of the Texas and massive flooding has been the result. Another tropical system is riding up along the Southeast US coastline today and it’ll actually head to the Outer Banks of North Carolina before turning away from the coast and out to sea.
