Some meteorologists were commenting on Isaac and said it has set a record for the tropical storm with the lowest barometric pressure. A storm with a pressure of 976 mb should be a hurricane. Isaac is one meteorologists are going to study for a long time.
So, where does the storm go from here? Here is the current position and forecast path.
Here is a forecast of wind gust speeds at 6pm this evening. The storm is predicted to be a hurricane at this point.
The National Weather Service's rainfall forecast shows nearly a foot and a half falling in New Orleans and in coastal Mississippi. Residents near rivers and streams should prepare for serious flooding.
There is nearly a 100% chance of a 4' or higher storm surge along the path of Isaac.
And, there is -- depending on location -- as much as a 60% of the surge exceeding 7'.
Finally, there is a risk of tornadoes later today. The 5% area is where the threat is most significant.
Bottom line: Isaac should strengthen into a hurricane before the eye makes landfall. Whether it ever achieves that status, the combination of excessive rainfall and storm surge will cause major flooding in many areas. If you are being advised to evacuate, follow that advice.
