She’s forecast to weaken over the next few days, but on Sunday Amanda entered the record books as the strongest Eastern Pacific hurricane ever seen in the month of May.
As of Tuesday morning, Hurricane Amanda’s maximum sustained winds were pegged at 120 miles per hour, making it a Category 3 storm. But on Sunday, she was much stronger than that.Â According to Wunderground.com meteorologist Jeff Masters:
Amanda peaked as a top-end Category 4 hurricane with 155 mph winds at 15 UTC (10 am EST) May 25, beating the previous May record holder,Â Hurricane Adolph of 2001,Â which reached a peak intensity of 145 mph on May 29th of that year.Â The earliest Category 5 storm on record in the Eastern Pacific wasÂ Hurricane Ava of 1973, which peaked at 160 mph on June 6, 1973. All three years (2014, 2001, and 1973) had ocean temperatures that were unusually warm for May along the path of these intense hurricanes: at least 0.4Â°C above average.
Waters in the tropical Eastern Pacific have been warming recently, increasing the odds of an El NiÃ±o.
Amanda became a tropical depression on Thursday, May 22 over relatively warm waters and with low wind shear â€” conditions that were conducive to rapid strengthening.
From here on out, Amanda is forecast to track north by northwest, gradually weakening as she travels over cooler water and then making an abrupt turn toward the southwest:
That turn to the southwest means Amanda poses no significant threat to land. But moisture from the storm may stream into Mexico and further north into the Southwestern United States, enhancing thunderstorm activity there. The moisture is needed desperately. (But not the lightning activity, which could ignite wildfires.)
