Bud was a tropical storm in the North Pacific Ocean late Wednesday Eastern time, the National Hurricane Center said in its latest advisory.
The tropical storm had sustained wind speeds of 40 miles per hour.
All times on the map are Eastern.
Bud is the second named storm to form in the Eastern Pacific in 2024.
Storms that form in the Atlantic or the Pacific generally move west, meaning Atlantic storms pose a greater threat to North America. If a storm forms in the Pacific close to land, it can bring damaging winds and rain before pushing out to sea.
What does the storm look like from above?
Satellite imagery can help determine the strength, size and cohesion of a storm. The stronger a storm becomes, the more likely an eye will form in the center. When the eye looks symmetrical, that often means the storm is not encountering anything to weaken it.
However, an air mass can sometimes block a storm, driving it north or northeast toward the Baja California peninsula and the west coast of Mexico. Occasionally, a storm can move farther north, as Hurricane Hilary did last year, bringing damaging winds and intense rain to Southern California.
Hurricane season in the Eastern Pacific began on May 15, two weeks before the Atlantic season started. Both seasons run through Nov. 30.
Another factor for storm-watchers this year is the likely development of La Niña, the intermittent, large-scale atmospheric pattern that can affect weather worldwide.
In the Pacific Ocean, La Niña increases wind shear, which is a change in wind speed and/or direction with height. Those changes make it more difficult for storms to form. (In the Atlantic, La Niña has the opposite effect, reducing wind shear and increasing the chances for storm formation.)
Sources and notes
Tracking map Source: National Hurricane Center | Notes: The map shows probabilities of at least 5 percent. The forecast is for up to five days, with that time span starting up to three hours before the reported time that the storm reaches its latest location. Wind speed probability data is not available north of 60.25 degrees north latitude.
Wind arrivals table Sources: New York Times analysis of National Hurricane Center data (arrival times); U.S. Census Bureau and Natural Earth (geographic locations); Google (time zones) | Notes: The table shows predicted arrival times of sustained, damaging winds of 58 m.p.h. or more for select cities with a chance of such winds reaching them. If damaging winds reach a location, there is no more than a 10 percent chance that they will arrive before the “earliest reasonable” time and a 50 percent chance they will arrive before the “most likely” time.

The actual areas that could become flooded may differ from the areas shown on this map. This map accounts for tides, but not waves and not flooding caused by rainfall. The map also includes intertidal areas, which routinely flood during typical high tides.
