Tropical Storm Matthew etc. 9/24/2010 4:30am

Colleagues, The only storm that matters at this point is Matthew. Lisa is in the far eastern Atlantic and a threat to nothing, and there is a area of interest in Caribbean, but not doing much, but Matthew may be a player.

FORECAST: Tropical Storm Matthew will make landfall in in Central America as a Tropical Storm with winds approaching 60 mph. Matthew will skirt the coast and get into the Yucatan Peninsula as a Tropical Storm / Tropical Depression early next week. Then, that is where questions begin.

DISCUSSION: Matthew is on the south side, and being steered by a subtropical ridge for the next 2 days. Then... we have conflicting forces for control. A developing low in the Central America would steer it to the SW. Yet, there is a tough that is centered near the east USA coast that extends down into Texas and beyond. It is weak this far south, but if the developing low in Central America is delayed, then the trough will exert the dominating influence. This should be clear Sat or Sun. It will determine whether Matthew dies in Mexico or Central America or gets into the Gulf and heads to be our first landfall this season. If it gets into the Gulf, it will become a hurricane. I would have waited a day or so, except today is Friday and I wanted to give you a heads up that what is now a very slow distant storm could become significant in the following weekend. But things will be a lot clearer by Sunday or before.

NEXT FORECAST: Saturday or Sunday

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.
