Tropical Storm IGOR 9/11/10 7 am

Colleagues, FORECAST: Tropical Storm IGOR has reagin its strength and is continue to strengthen, becoming a hurricane later today and a major hurricane Tuesday. I still think IGOR will miss Florida and probably all the USA as all indications it will follow a path similar to those of the last three systems this Summer. Present position is 750 miles west of the Cape Verde Islands. Winds are 70 mph (nearly a hurricane), and while the movement is now West, my mid week it should veer north wards as it approaches the Windward islands. It is gets pass 20N before it gets to 60W, we are safe. To do that, the turn will have to start before Wednesday.

The disturbance in the Windward Islands is slowly moving into the Caribbean Sea and slowly gaining strength. At this time it does not appear to be a threat to Florida, but it bears watching.

DISCUSSION: IGOR will continue to strengthen. All environmental conditions support strengthening. IGOR is moving at a crisp 20 mph. by mid week, IGOR should be a Major hurricane (Category 3). By mid week I should know if any part of the USA is threatened. At this point, no. By Wed, IGOR should be rounding the western edge of the subtropical ridge and entering a trough region. which will gradually swing the major storm to the NW and recurve as it approaches the mid-latitude westerlies, ultimately being caught up in a frontal system currently in the mid-west.

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.
