The transition is here. Tropical season is winding down and winter weather is starting to show.
Several factors come into play for the downward spiral of tropical activity which officially ends on the last day of this month. Water temperatures over the Atlantic basin have peaked and are cooling off. Next the jet stream is strengthening, leading to more wind shear, which is unfavorable for development. Last, dry air is becoming more common, which is inhibiting development.
Despite the decline of tropical activity, a few notable hurricanes have formed at the end of October.
