Synopsis for the E Pacific within 250 nm of Mexico
326 PM PDT Mon Sep 23 2024

.SYNOPSIS...
Recently upgraded Hurricane John is centered near 15.5N 98.5W at
23/2100 UTC, moving north at 5 kt. Estimated minimum central
pressure is 973 mb. Maximum sustained wind speed is 85 kt with
gusts to 105 kt. Hurricane-force winds extend outward up to 10
NM from the center and tropical-storm-force winds extend outward
up to 40 NM. Seas 12 ft or greater are occurring within 75 NM in
the southern semicircle, within 60 NM in the northeast quadrant
and within 45 NM in the northwest quadrant, with peak seas near
16 ft. Strong convection is occurring within 90 NM of the center,
except within 150 NM to the east of the center. Rapid
strengthening is forecast, and John is expected to become a major
hurricane before the center reaches the coast of southern Mexico
on Tuesday. John will move to 16.0N 98.3W Tue morning, inland to
16.5N 98.3W Tue afternoon, move inland and weaken to a tropical
depression near 16.7N 98.4W Wed morning, and dissipate Wed
afternoon. Elsewhere, high pressure will become anchored near
20N140W through Tue, leading to gentle to moderate N winds in the
offshore waters. By Wed, the pressure gradient between the
persistent high pressure and falling pressure in the southwestern
United States will support fresh NW winds and seas of 5-7 ft in
the Mexican offshore waters, likely occurring into the upcoming
weekend.
