The primary USA corn and soybean crops lie far from the areas of direct impact, but the grain markets could experience indirect effects of Irma as it is likely to disrupt logistics, particularly the movement of supply to both feed mills and ports.
A Category 3 hurricane means sustained winds of 111 miles per hour to 129 miles per hour will occur. If the Bermuda high is exceptionally high, then the pressure difference between that and the hurricane is much larger, which leads to stronger winds.

The National Hurricane Center also said a tropical storm watch was in effect for the island nation of St. Kitts and Nevis, the British territories of Anguilla and Montserrat, and the islands of Saba and St. Eustatius, which are part of the Netherlands.
Jose has been upgraded to a Category 3 hurricane.
Experts are predicting that this will be the most devastating storm to hit Florida since 1992.
