Peak of the Season
Atlantic Region (ATLN)

Weekly analyses of tropical systems passing through the Atlantic Region.
In the two graphs below are the total number of tropical systems plotted which were passing by for each seven day period since 1851 or since 1944 through 2010. So it can be easily seen which part of the year is most active. Those tropical systems reaching hurricane strength are in red, and the 'big ones' (severe hurricanes, or category 3 and up) in purple. A summary below the graph shows during which week of the year the most number of tropical storms passed by, as well as the peak of the season for hurricanes and severe hurricanes. Between brackets the number of storms during that week, and the probability of it occurring (for example, if 2 hurricanes came close during that week over 10 years, the probability of a hurricane passing by for that specific week is one every 5 years).
See how this compares to all Atlantic storms, or for the Eastern Caribbean, Western Caribbean or the Bahamas/Turks&Caicos regions.

A separate part of the climatology section contains the actual storm tracks (all or per decade) and a 5 year analysis to find out if more storms have passed through the Atlantic Region lately. See also how the Atlantic Region ranks among other regions/islands.
