At the bottom left is Hurricane Bud in the eastern Pacific.
At Category 3, Bud was classified as a major hurricane. According to the NHC, Hurricane Bud is expected to move north-northwest on Tuesday into the midweek.
However, forecasters said conditions could be a bit more favorable for it to develop when and if it gets into the southwestern Gulf by the end of the week. Rainfall of 3 to 6 inches, with isolated patches of 10 inches, was possible into Tuesday afternoon.
Bud has 120 miles per hour maximum sustained winds and was moving northwest at 7 miles per hour, the NHC said.
The Mexican government discontinued the tropical storm watch for Manzanillo to Cabo Corrientes, the NHC said.
The rain could cause life-threatening flash floods and mudslides, forecasters said.
The Hurricane Center said the storm could generate swells that cause life-threatening surf and rip currents over the coming days along Mexico's southwestern coast.
Both depressions come in the wake of tropical storm Alberto, which slammed into Mexico, the Caribbean and the U.S. in late May, killing 10 people.
The Weather Channel reported that the hurricane could prompt a "surge of moisture" in the southwest United States, which would lead to an increase in rain showers and storms.
A system has to have a closed center of circulation and winds of at least 39 miles per hour to be considered a tropical storm and get a name.
On top of Irma and Maria, powerful category 4 hurricane Harvey inflicted $125billion worth of damage, mostly from catastrophic flooding in Houston, Texas, between August and September past year. The depression is now located about 665 miles southwest of the southern tip of Baja California with maximum sustained winds of 35 miles per hour.
