Overview
- The National Hurricane Center assesses a nearly 100% probability that Tropical Depression 1-E will strengthen into Tropical Storm Alvin within 48 hours.
- Its emergence marks an early onset of the Eastern Pacific hurricane season, which began May 15, ahead of the basin’s average first storm date of June 10.
- Forecast models indicate Alvin will deliver locally heavy rainfall and gusty winds to Mexico’s west-central coast from late week into the weekend.
- Remnant moisture from Alvin is likely to track northward, bringing increased cloud cover and scattered showers to Southern California, Arizona and adjacent U.S. regions.
- NOAA outlooks predict 14 to 18 tropical storms and 7 to 10 hurricanes in the Eastern Pacific this year, while the Atlantic season is expected to produce 13 to 19 named storms.
