Intensity Measures Position & Heading Landfall (NHC)

Max Sustained Wind 200 mph Position Relative to 125 miles SW of Manzanillo Speed: (category 5) Land: 195 miles S of Cabo Corrientes Today between Puerto Est. Time & Region: Vallarta and Manzanillo Min Central Pressure: 880 mb Coordinates: 17.6 N, 105.5 W

Trop. Storm Force Est. Max Sustained Wind 155 mph or greater 175 miles Bearing/Speed: N or 5 degrees at 10 mph Winds Extent: Speed: (category 5) Forecast Summary  The NHC forecast map (below left) shows Patricia making landfall later today on southwestern Mexico as a major hurricane (category 3+).  The windfield map (below right) is based on the NHC’s forecast track which is shown in bold black. To illustrate the uncertainty in Patricia’s forecast track, forecast tracks for all current models are shown in pale gray.  Hurricane conditions should reach the hurricane warning area during the next several hours, with the worst conditions likely this afternoon and this evening. Tropical storm conditions are now spreading across portions of the warning area. Hurricane conditions are also possible in the hurricane watch area today.  Patricia is expected to produce total rainfall accumulations of 8-12 inches, with isolated maximum amounts of 20 inches, over the Mexican states of Nayarit, Jalisco, Colima, Michoacan and Guerrero through Saturday. These rains could produce life-threatening flash floods and mud slides.  An extremely dangerous storm surge is expected to produce significant coastal flooding near and to the right of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. Swells generated by Patricia are likely to cause life-threatening surf and rip current conditions.

Coastal Watches and Warnings A Hurricane Warning - meaning that hurricane conditions are expected somewhere within the warning area, in this case within about 24 hours - is in effect for San Blas to Punta San Telmo. A Hurricane Watch – meaning that hurricane conditions are possible within the watch area - is in effect for East of Punta San Telmo to Lazaro Cardenas.

Tropical Storm Wind Speed Probabilities at 5 AM PDT Friday, October 23, for the next five days The maps below show probabilities of maximum sustained wind speeds over the next five days. The map at lower left shows a large swath of southwestern Mexico with greater than 90% chance of seeing maximum sustained wind speeds of 39 mph or greater. The map at lower right shows a smaller area with significant chances of seeing maximum sustained wind speeds greater than 74 mph.

NHC Estimates of New Atlantic Tropical Cyclone Formation National Hurricane Center The map at right illustrates the NHC’s estimate of tropical cyclone formation Tropical Cyclone Formation Estimates on October 23, 2015 potential over the next 48 hours in the Eastern Pacific.

There are currently no such areas shown on the map. But the NHC notes that an area of low pressure could form several hundred miles south-southwest of the southern tip of the Baja California peninsula over the weekend. Development of this system is expected to be slow to occur during the next few days while it moves slowly toward the east-northeast or northeast. Formation chance through 48 hours is low at 10 percent. And formation chance through 5 days is also low at 20 percent.
