In this 3-D Flyby animation, NASA analyzed the rainfall rates within Tropical Storm Aletta on June 6, 2018 at 0046 UTC (June 5 at 8:46 p.m. EDT).
David Zelinsky, a forecaster at the U.S. National Hurricane Center (NHC), said Aletta's maximum sustained winds have increased to 220 kilometers (140 miles) per hour. Tropical Storm Aletta was last clocked with 60 miles per hour sustained wind speeds.
For now, it is too soon for experts to know whether this second storm would pose any direct threat to the Mexican Pacific next week.
The west coast of Baja California Sur will be affected with high swells and rip currents this weekend.
AccuWeather Hurricane Expert Dan Kottlowski said: "Since this system will track over and through an environment very similar to what Aletta experienced, there's a good chance that it will become a hurricane".
If it becomes a tropical storm, it will be named Bud.
Mexico's National Water Commission (Conagua) is predicting 32 hurricanes for this season, four more than average, with 18 in the Pacific and 14 in the Atlantic. "It's happened 3 other times this decade, and a total of 9 times since 1970, per NOAA's database", he tweeted. If the disturbance earns a name, it will be called Bud.
While it may seem odd for the Pacific's first storm to be so strong, Weather.com meteorologist Jonathan Erdman discovered it's not all that uncommon.
