Hurricane Fabio continues to churn over the open waters of the Eastern Pacific as it tracks toward the northwest this afternoon.
AccuWeather.com meteorologists expect Hurricane Fabio begin the weakening process this evening as the system tracks into cooler waters.
While the majority of tropical systems that form near the Central America coast in the Eastern Pacific head into the open sea, every once in awhile a storm will manage to take a more northward turn.
As high pressure to the west of Fabio seeps towards the east, Fabio will take a turn towards the north and across the aforementioned cooler waters.
According to Tropical Weather Expert Dan Kottlowski, "Cooler waters in this region would lead to substantial weakening of Fabio. But moisture from it could be drawn in across the Mexico province and perhaps part of the southwestern United States moving forward."
Fabio is expected to weaken even further by Tuesday or Wednesday into either a tropical depression or remnant low as it loses its tropical characteristics over the cooler waters.
Although the current track keeps Fabio away from land, moisture associated with the storm will be pulled northward into parts of the Desert Southwest by the middle of the week.
The additional moisture from Fabio will add to the already monsoonal moisture that has led to localized drenching thunderstorms across the Southwest.
An unusually strong push of cool air for early September will move southward along the Atlantic Seaboard into the Labor Day weekend, before July-like heat returns by next week.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Nino.
After heat has dominated headlines this summer, cool air has finally taken control of the northern half of Europe with no signs of departing anytime soon.
Steering winds could take Ignacio, as a remnant storm, into the southeastern arm of Alaska or British Columbia during the middle days of next week.
While Tropical Storm Kevin will stay well away from Mexico, its moisture will still lead to an increase in showers and thunderstorms from Baja California to the Four Corners region of the United States.
A stormy weather pattern will prevail through September across much of southern South America.
