A 10 foot storm surge invaded Plaquemines Parish, the Mississippi Delta region that juts out into the Gulf of Mexico. NBC news reports 50 to 75 people were rescued in Plaquemines, some pulled from attics by boat.
Overall the pumps and flood gates appear to have worked as designed in New Orleans. That’s great news 7 years to the day after Katrina flooded the city.
Isaac’s rains are a good news bad news scenario for many.
The bad news is 5″ to 8″+ rainfall totals will cause short term flooding.
The good news is that as Isaac spins north, 6″ to 8″ rainfall totals fan out in an arc from Arkansas to St. Louis and central Illinois toward Indy. There arras are in severe to extreme drought and can use some heavy soaking rains.
It may be too late for crops this year, but Isaac will recharge soils and rivers and may be a big step toward preventing a multi-year drought in some parts of the Midwest.

A cool front will slide south a little earlier than the models indicated on Thursday…and that should save Minnesota from triple digit heat Thursday.
Still days 27 & 28 of 90+ heat this summer is the highest number in over 5 years. We sweated through 27 days of 90+ heat back in 2007.
Is it just me, or does 93 degrees actually feel pretty good now?
