Tropical Storm Tomas 10/30/2010 8:00am

Colleagues, FORECAST: Tropical Storm TOMAS has formed just east of the Leeward Islands. Maximum Sustained Winds (msw) are 70 mph and TOMAS will become HURRICANE TOMAS over night. Movement is WNW and it is basically headed for now toward Jamaica. Over the next next week, expect steady strengthening of the Hurricane. TOMAS will pass south of Puerto Rico and just south of Hispaniola. There is no way for Haiti to be spared at least rain and strong winds. This will be mid to latter part of next week. At that point their will be a movement to the north ... or not.

DISCUSSION: This hurricane has the potential to make landfall in the USA early next week. The movement and intensity (strengthening) through most of this upcoming week are clear. A trough will be leaving the scene, and a ridge will be building in it's place, creating generally WNW movement, and strengthening. However, a new trough will be entering the scene mid to late next week and control of the steering flow will ensue. At this point, it could turn north around eastern Haiti, or continue WNW toward Jamaica, or veer to the south toward the Yucatan Channel. The better models have not given much credit to the encroaching trough. Not sure why and will be looking more closely at that over the weekend. At this point, there is the possibility that this storm could get into the Gulf, but it is too early with this uncertainty (at this point) of what will happen in 5 days from now. At this juncture, I see it moving westward a few days longer into next weekend, and then turning north, but that is based on some speculation on data that is not yet available.

Elsewhere in the US, weather is seasonal, with no weather threats. Colder weather is invading the southeast with temperatures now in the low 40s (morning temperature) but getting up to a beautiful lower 70s today. High 70s today in north Florida to low 80s in the south today. Beautiful day. No rain in Florida or the Southeast.

NEXT FORECAST: Sunday morning

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.
