Tropical Storm Isaac 8/27/2012 4:30 am

Colleagues, Threat to Tampa is minimal as Isaac heads to New Orleans. FORECAST: Tropical Storm Isaac about 350 miles south of Tallahassee headed NW with winds of 65 mph. Just made a jog to the west and has slowed to about 13 mph. Isaac will slowly intensify. Close to landfall some models show a jog to the east (like Katrina did), but I don't believe it. I think it will make landfall going NW to the west of New Orleans, which is not good good for New Orleans. It will be a Category 1 at landfall. Mississippi and Alabama will experience significant storm surge and sustained tropical storm force winds. Western Florida Panhandle will experience tropical storm force gusts and all the panhandle rough seas and elevated storm surge of a few feet, but not like it looked just a few days ago. Tampa will continue to have rain, occasionally heavy, but not more than squall lines. Weather in Peninsular Florida will be gradually improving, but with occasional heavy rain especially today and through tomorrow. No sustained tropical storm force winds in Florida, but gusts can easily reach those levels.

The rain has largely left the immediate Miami area, but heavy rain and strong gusts will continue from Fort Lauderdale up the coast, moving north and becoming less with time. Rain should reach the panhandle later today. This storm is more wide than intense so all of Florida can expect some occasional heavy rain.

DISCUSSION: Isaac is off the radar now until it get closer to New Orleans.

NEXT FORECAST: Tomorrow, Tuesday, August 28, sooner if new data comes in that would allow refinement. I will be watching the data come in constantly until after landfall.

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.
