AccuWeather.com reports while from a core meteorological standpoint Isaac will not be another Katrina in terms of intensity, it is still a dangerous storm.
Isaac is forecast by AccuWeather.com to make landfall as a hurricane in Louisiana and will bring the risk of storm surge flooding, inland flooding, damaging wind and beach erosion to part of the central Gulf Coast area.
According to AccuWeather.com Hurricane Expert Dan Kottlowski, "The angle at which Isaac could come ashore could still drive a substantial amount of water inland quickly over southeastern Louisiana and southern Mississippi." As a result a relatively weaker storm (Category 1 or 2), when compared to Katrina (Category 3 at landfall in La./Miss.), could still pack a considerable punch.
Isaac will test the New Orleans levees. Katrina moved up from the south over the Mississippi Delta on a curved path. Isaac is likely to be rolling in straight from the southeast, so the counterclockwise flow around the storm could drive a significant surge toward Chanderleur Sound, Lake Borgne and Lake Pontchartrain early on.
