"Fujiwara Effect" Impacted Emilia and Fabio in E. Pacific

The Eastern Pacific has been busy with tropical activity. The good news is that they are fish storms, which means NO impacts to land are in the forecast. On Monday, tropical storms Carlotta, Daniel, Emilia, and Fabio were all spinning out in the Pacific. It was the first time since the 1970s that there have been four named storms simultaneously.

In the Eastern Pacific, we are now left with Tropical Storm Emilia. Fabio weakened quickly because of some interaction previously with Emilia. This term is called the "Fujiwara effect". According to the National Weather Service glossary, this happens when two tropical systems spinning close enough to one another "begin an intense dance around their common center". Typically if one system is stronger, the strong system will absorb the weaker one. In this case, Emilia has taken some of Fabio's intensity because of their interaction. Fabio has now become a Post-Tropical Cyclone.

In Central America, just south of Mexico, there is also a tropical wave to watch that is expected to emerge into the far eastern Pacific sometime Thursday.

The Eastern Pacific Hurricane Season has two distinct peaks in mid-August and again in mid-September. This season is anticipated to be below average in the Eastern Pacific. At the same time, it will be average for tropical activity in the Atlantic due to a La Nina forming during the peak of hurricane season in September. It only takes one storm to impact you and the time to prepare is before the storm hits.
