Synopsis for the E Pacific within 250 nm of Mexico
329 PM PDT Wed Jul 30 2025

.SYNOPSIS...A trough of low pressure, EP99, is located several
hundred miles southwest of the southwestern coast of Mexico.
Environmental conditions appear conducive for additional
development, and a tropical depression is likely to form during
the next day or two while the system moves west-northwestward
around 15 mph, remaining well offshore of the southwestern coast
of Mexico. There is a high chance of tropical development within
the next 48 hours. Elsewhere, fresh to strong N to NE winds will
pulse in the Gulf of Tehuantepec through this weekend, with the
strongest winds occurring each night and early morning. Winds
will diminish in this region by early next week. Elsewhere,
moderate to fresh NW winds, with locally strong winds, will occur
offshore of Baja California through this weekend.
