Synopsis for the E Pacific within 250 nm of Mexico
901 AM PDT Sun Oct 1 2023

.SYNOPSIS...Moderate seas will not vary much into the middle of 
the week. Fresh to strong N winds will pulse in the immediate 
area of the Gulf of Tehuantepec, mainly at night, through 
tonight, then moderate to occasionally fresh thereafter. Fresh to
strong SW winds in the northern Gulf of California will pulse 
through tonight. Winds will be moderate or weaker elsewhere 
through the early part of the week. Looking ahead, environmental 
conditions around a tropical wave currently along 101W are 
expected to be favorable for development of this system during 
the next several days, and a tropical depression is likely to 
form during the middle part of next week while it moves generally
northwestward. The system has a medium chance of tropical 
development within the next 48 hours, and a high chance in 7 
days. Please refer to the latest NHC Tropical Weather Outlook at 
hurricanes.gov for the latest on this system.
