DISCUSSION AND OUTLOOK ---------------------- At 800 PM MST (0300 UTC), the center of Post-Tropical Cyclone Xavier was located near latitude 19.1 North, longitude 107.5 West. The post-tropical cyclone is moving toward the west-northwest near 6 mph (9 km/h). The system is expected to turn toward the west or west- southwest at about the same forward speed during the next couple of days. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Some weakening is forecast during the next 48 hours and Xavier is expected to become a remnant low by Tuesday evening. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Xavier will continue to affect portions of the coast of southwestern Mexico this evening and should subside on Tuesday morning. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office.

Post-Tropical Cyclone Oscar Forecast Discussion Number 20

2018-10-31 21:35:03| National Hurricane Center (Atlantic)

Issued at 500 PM AST Wed Oct 31 2018 000 WTNT41 KNHC 312034 TCDAT1 Post-Tropical Cyclone Oscar Discussion Number 20 NWS National Hurricane Center Miami FL AL162018 500 PM AST Wed Oct 31 2018 Satellite imagery and scatterometer data indicate that Oscar has become a hurricane-force extratropical low, as the central convection has all but dissipated and frontal-band-type cloud features have become better defined. The scatterometer data show hurricane-force winds about 70 n mi south of the center, and that the overall wind field has expanded considerably since the previous overpass. The cyclone is expected to maintain an intensity of 60-65 kt for the next 48 h, then gradually weaken as the baroclinic energy wanes, with dissipation occurring between 96-120 h over the far northeastern Atlantic. The initial motion is now 030/30 kt. Oscar is now well embedded in the mid-latitude westerlies, and for the next 3-4 days it should move generally northeastward with a gradual decrease in forward speed. Much of the current forecast, especially the intensity and the size, is based on input from the NOAA Ocean Prediction Center. This is the last advisory on Oscar from the National Hurricane Center. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and available on the Web at https://ocean.weather.gov/shtml/NFDHSFAT1.shtml.
