Discussion

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. If there is any impact from the much-weakened remains of Irma in the Mid-Atlantic region, it would likely be in the Tuesday/Wednesday time period.
