Synopsis for the E Pacific within 250 nm of Mexico
830 PM PDT Tue May 20 2025

.SYNOPSIS...Fresh NW winds will pulse offshore of Cabo San Lucas
each night through this weekend as troughing prevails over Baja 
California Sur. Elsewhere, occasional fresh NW winds are expected
north of Punta Eugenia into this weekend as low pressure remains
over coastal Southern California. Rough seas generated by strong
winds north of the area will occur offshore of Baja California 
Norte through Sat before seas slowly subside. Looking ahead, an 
area of low pressure could form by this weekend or early next 
week several hundred miles south of the southern coast of Mexico.
Conditions appear favorable for some development of this system 
thereafter while it moves westward to west-northwestward at 
around 10 to 15 mph. This system has a low chance of tropical 
cyclone development through 7 days.
