The Eastern Pacific hurricane season approaches, and significant changes are anticipated this summer. NOAA’s Climate Prediction Center (CPC) has identified a potential area for tropical development off the southern coast of Mexico. With just over two weeks until the season officially starts, the prospects for intensified storm activity are rising.
Impending El Niño and Hurricane Season
The developing El Niño climate pattern is projected to enhance the number of named storms in the Eastern Pacific. The CPC has highlighted a time frame between May 13 and May 19 when a tropical system may emerge off Mexico’s coast.
Current Sea Surface Temperatures
- Sea surface temperatures in the Pacific are currently above average.
- Localized regions are reaching upper 80s Fahrenheit, which is optimal for tropical development.
- Average temperatures are about 2 to 3 degrees higher than typical, reinforcing the likelihood of cyclone formation.
Typically, the first named storm tends to form around June 10. However, with the existing warm water conditions and the expected strengthening of El Niño, this season could be uniquely active.
Comparison with Past Events
Recent warm waters significantly bolstered Super Typhoon Sinlaku, which struck the Northern Mariana Islands with winds nearing 200 mph. Historically, El Niño years, on average, yield more storm activity.
| Average Storms in the Eastern Pacific | El Niño Years |
|---|---|
| 15 Named Storms | 17 Named Storms |
| 8 Hurricanes | 9 Hurricanes |
| 4 Major Hurricanes (Category 3+) | 5 Major Hurricanes |
El Niño’s Role in Hurricane Activity
El Niño influences storm patterns differently across various ocean basins. While it tends to lessen hurricane activity in the Atlantic, it fuels tropical storms and hurricanes in the Eastern Pacific. The warmer water promotes rising warm air, which is critical for cloud and thunderstorm formation needed for hurricanes.
Given the predictions of a super El Niño, experts assert that this could lead to a notably active hurricane season, surpassing typical expectations.
Conclusion
The Eastern Pacific hurricane season runs from May 15 to November 30. With the potential for intensified storm activity linked to the developing El Niño, residents in coastal areas should remain vigilant and prepared for the upcoming season.
