This hurricane name too will be retired once the saga of Isaac plays out. As of early Tuesday morning, here are 2 satellite pictures of Isaac just 100 SSE of the mouth of the Mississippi River moving to the NW at 7 mph. Technically a tropical storm, Isaac's winds and storm surge along with its low 976 mb pressure will make this undoubtedly a hurricane. We're splitting hairs here on this one. Listen, if you were in Cajun country, this ain't just your ord'nary typical ocean blow!
You can sorta see an eye developing (green) with the deep convection (red) around this developing eye.
From the above satellite pic, there is some dry air trying to become entrained into the system which may help inhibit the rapid intensification of Isaac as it approaches landfall. Time will tell...
As Isaac approaches the continent, here is a map from the NWS from New Orleans describing the impacts of the potential flooding and storm surge as the ocean water gets piled onshore. Here's hoping the newly reconstructed levees help keep the majority of New Orleans from being inundated once again.
The map below shows the exact landfall region as per the guys from HPC...that is one scary track for the city of New Orleans...
And here is the Geophysical Fluid Dynamics Lab's model for where Isaac will go once ashore...
With that above map in mind, here is what HPC suggests as rainfall totals over the next several days...through early Sunday morning.
Most of our region around the Harrisburg area will receive some effects from the remnants of Isaac as there will be a "triple point" low pressure system reflected at the surface of the earth come Labor Day. Synoptically, whenever a map looks like the one below, moderate to heavy rain will fall over our region...Take a look below.
OK....gotta run...this school thing kinda cramps my wx hobby...but was able to keep my loyal minions informed! And not only that, the school thing keeps food on the table!
Enjoy your Tuesday!

AA: Isaac to adversely affect New Orleans! Could be nastier than Katrina! It's remnants will head our way for later this Labor Day weekend.
