Isaac is still a tropical storm, but will likely become a hurricane within the next 24 hours. The storm is expected to remain a strong category 1 hurricane until landfall near New Orleans. Go here for the latest track from the National Hurricane Center.
Isaac will likely be making landfall just a few hours off on the same date as Hurricane Katrina, seven years ago, but thankfully as much weaker storm.
The current track takes the weakening storm inland into the lower Mississippi Valley and into Arkansas by Friday. The remnants of Isaac are then picked up by an approaching mid-level wave (trough) and possibly pushed through the Ohio Valley/Great Lakes region Saturday and Sunday. The first map is Saturday, the second map is Sunday, both showing the GFS model precipitation chances around our area. The last map is the current weather model forecast paths. While the leftovers of tropical systems can bring severe weather, we do not expect a repeat of what Ike brought in 2008. Time will tell where Isaac eventually decides to go, and we'll keep fine-tuning the track through the workweek. Stay tuned!
