These dates, adopted by convention, historically delimit the period in each year when most tropical systems form.

That same month, on the opposite side of the country, Hurricane Manuel made multiple landfalls along Mexico's Pacific coast, causing catastrophic damage.

After coming ashore in Florida's Big Bend region, it killed at least three and brought tornadoes, heavy rainfall, and flooding to a large section of the U.S. East Coast and Atlantic Canada.

Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (knots, miles, or kilometers), following the convention used in the National Hurricane Center's products.
