Tropical Storm Amanda Forms Offshore as First Named Storm of Pacific Season

Forecasters say warmer Pacific waters from a developing El Niño raise odds of an above‑normal eastern Pacific hurricane season.

Overview

  • Tropical Storm Amanda formed from Tropical Depression One‑E on Wednesday, June 3, and was centered roughly 1,300–1,475 miles west‑southwest of Baja California with maximum sustained winds near 40 mph while remaining well offshore.
  • The National Hurricane Center says Amanda will likely strengthen modestly over the next 48–72 hours before weakening this weekend as it moves into stronger upper‑level winds and cooler sea surface temperatures and is expected to dissipate next week.
  • Forecasters are also tracking two other eastern Pacific disturbances that the NHC gives about a 50% and a 20% chance of developing into tropical cyclones within seven days.
  • NOAA’s seasonal outlook projects an above‑normal eastern Pacific season with about 15–22 named storms, 9–14 hurricanes and 5–9 major hurricanes, citing sea surface temperatures roughly 2–3°F above average and a high probability of El Niño developing by midsummer.
  • Amanda poses no immediate land threat but its formation underlines risks that a busier Pacific can bring heavier rain, surf and flooding to parts of Mexico, Central America or Hawaii and can increase upper‑level winds that tend to reduce hurricane activity in the Atlantic.
