Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sun Jul 2 2023

For the eastern North Pacific...east of 140 degrees west longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Adrian, located several hundred miles west-southwest of
the southern tip of the Baja California peninsula.

Offshore of Southern Mexico:
A broad area of low pressure could form several hundred miles off
the coast of southern Mexico during the middle to latter part of
this week. Thereafter, environmental conditions are forecast to be
conducive for gradual development of this system and a tropical
depression could form while it moves generally west-northwestward,
roughly parallel to the southern and southwestern coasts of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

The low-level center is decoupled from a limited area of active convection over the western portion of the circulation. Adrian is passing just to the north of Clarion Island, and a Mexican Navy automated weather station has recently reported sustained tropical-storm-force winds with a gust of 48 kt. The objective and subjective satellite estimates have continued to fall this afternoon, with T3.0 Dvorak data-T numbers from TAFB and SAB along with ADT, AiDT, and SATCON objective estimates between 47-53 kt. Based on these data, the initial intensity is lowered to 50 kt for this advisory. The storm is still moving west-northwestward at around 300/6 kt. A gradual turn toward the west is expected over the next couple of days as the vortex spins down and becomes increasingly steered by the low-level trade wind flow. Further weakening is expected due to continued easterly shear, decreasing SSTs, and a drier and more stable air mass along the forecast track. The official NHC forecast now shows Adrian degenerating to a remnant low in 24 h, with dissipation early next week. This updated forecast is very similar to the previous one with no other notable changes.

HAZARDS AFFECTING LAND ---------------------- RAINFALL: Through Monday, storm total rainfall of 3 to 5 inches, with maximum amounts of 8 inches, is expected across portions of southern and western Mexico from Colima northwest to Sinaloa and Durango in association with the remnants of Beatriz. This rainfall could lead to localized flash flooding and mudslides. SURF: Swells generated by Beatriz are expected to diminish along the southwestern coast of Mexico during the next day or so. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

For the eastern North Pacific...east of 140 degrees west longitude:

Active Systems:
The National Hurricane Center is issuing advisories on recently
downgraded Tropical Storm Adrian, located several hundred miles
southwest of the southern tip of the Baja California peninsula, and
has issued the last advisory on the remnants of Beatriz, located
near the coast of west-central Mexico.

Offshore of Southern Mexico:
A broad area of low pressure could form several hundred miles off
the coast of southern Mexico during the latter part of next week.
Some gradual development of this system is possible thereafter as it
moves generally west-northwestward, roughly parallel to the coasts
of southern and southwestern Mexico.

Since that time, the eye which had become apparent in satellite imagery has become obscured, and it's possible that the hurricane's structure is beginning to be affected by the nearby mountainous terrain of Mexico. Beatriz continues to move northwestward, or 305/11 kt, and that general motion should continue for the next 36 hours or so while the hurricane moves along the southwestern periphery of a mid-level ridge located over northern Mexico and the western Gulf of Mexico. On this trajectory, Beatriz will continue to graze the coast of southwestern Mexico during the next 24 hours, but any wobble to the right of the forecast track could bring the center inland during that time. If Beatriz survives the next 36 hours, another mid-tropospheric ridge is expected to build over the southwestern United States, causing the cyclone to turn west-northwestward and then westward and slow down on days 2 and 3. There is a fair amount of model spread during that period, and the updated NHC track forecast is closest to the GFS, TVCE, and HCCA aids, nudged a bit to the right of the previous forecast. Beatriz is expected to remain a hurricane during the next 24 hours if its center remains over water, but the mountainous terrain could cause some slow weakening regardless. After 36 hours, increasing shear, cooler sea surface temperatures, and a drier, more subsident atmosphere are expected to contribute to faster weakening as Beatriz moves away from west-central Mexico. Most of the global models, with the exception of the GFS, dissipate the circulation by day 3, so the new NHC forecast now shows Beatriz degenerating into a remnant low by day 3, with dissipation occurring by day 4. KEY MESSAGES: 1. Beatriz is forecast to remain a hurricane for the next day or so, bringing a risk of hurricane-force winds and a dangerous storm surge to portions of the southwestern coast of Mexico through Saturday afternoon. A Hurricane Warning remains in effect for portions of the coasts of Guerrero, Michoacan, Colima, and Jalisco. 2. Locally heavy rainfall is expected across southern and western Mexico from the state of Guerrero northwestward to the states of Sinaloa and Durango. These rains could lead to life-threatening flash flooding and mudslides.
