HURRICANE ISAAC 8/29/2012 4:30 am

Colleagues, Southern Louisiana and coastal Mississippi, Alabama, and Florida's western Panhandle will continue to be battered with tropical storm force winds and gust and squall with heavy rain and rough surf and high tides today. FORECAST: HURRICANE ISSAC made landfall over the Mississippi Delta just before midnight and now is making a second one to the West over Port Fourchon with winds of 80 mph. It is headed to the west of New Orleans toward Baton Rouge. It will slowly weaken and by late this afternoon should be downgraded to a tropical storm. Present movement is very slow but slowly will pick up. For much of Southern Louisiana and the Gulf coast, flooding is the major concern due to ISAAC's slow movement and the relentless heavy rain, especially to the east of the storm's center.

Mississippi, Alabama, and the Florida's western Panhandle will experience Tropical Storm force winds, strong gusts especially today and locally heavy rain. Storm surge along the Gulf Coast should begin to recede, particularly east of Apalachicola, some places slowly as surge is highly local. Western Florida and points west may have another day or so of high tides, but they should have, or should soon peak.

DISCUSSION: HURRICANE ISAAC is negotiating its way trough a weakness in ridge and in a couple of days will be picked up and accelerate to the north and then NE by an approaching trough. The peninsula of Florida no longer is under the influence of ISAAC, even though yesterday there were some strong local winds and rain. Different system.


DISCLAIMER: The Florida State University required that I not use any FSU equipment to send out these forecasts. To comply, I have purchased my own computer for making and sending these forecasts. I have been touched by the many offers of encouragement and support that I have received. I am deeply indebted to the Secretary and the staff of the Department of Children and Families who value these forecasts for the citizens of Florida. Also to the firm Hayes Computer Systems, which set up the distribution software and is providing for the distribution of these forecasts at no cost. They are very professional and competent. I acknowledge that these forecasts are mine alone, by my own effort and initiative. I only try to provide the best possible forecasts for the community, and the State of Florida and now, surrounding states at no cost to those who receive it.


I have set up a website and blog which may be reached at URL In this website you can find the forecast, as well as a blog of expanded interests of mine dealing with weather and climate and hurricanes, and an opportunity for you to comment as well. There is also an opportunity for you to contribute to defraying the increasing costs of maintaining this service, if and only if you want to. This must always be a not for profit public service and free as long as I have anything to do with it. But I have had offers of help in the past and it is increasingly difficult for me to underwrite all the cost, even with the generous and gracious support form Hayes Computer Systems.
