DISCUSSION AND OUTLOOK ---------------------- At 800 PM PDT (0300 UTC), the center of Hurricane Marie was located near latitude 17.5 North, longitude 125.7 West. Marie is moving toward the northwest near 9 mph (15 km/h). This general motion is expected to continue through most of the weekend. A turn toward the west-northwest is possible by early next week. Maximum sustained winds are near 130 mph (215 km/h) with higher gusts. Marie is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are possible through tonight, followed by weakening beginning on Saturday. This weakening trend will continue into early next week. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 948 mb (28.00 inches). HAZARDS AFFECTING LAND ---------------------- None.

Hurricane Marie Forecast Discussion Number 15

Issued at 200 PM PDT Fri Oct 02 2020 000 WTPZ43 KNHC 022041 TCDEP3 Hurricane Marie Discussion Number 15 NWS National Hurricane Center Miami FL EP182020 200 PM PDT Fri Oct 02 2020 Marie remains a powerful hurricane this afternoon. A 1530 UTC SSMIS 91 GHz microwave image showed a well-defined, closed eyewall with a 20 nm eye, which is still evident in recent GOES-17 visible and infrared satellite imagery. The initial intensity is held at 115 kt based on T6.0 Dvorak classifications from TAFB and SAB, which are consistent with recent ADT and earlier SATCON estimates. The 34-kt radii are expanded slightly with this package based on recent ASCAT data. Marie is moving west-northwestward (295 degrees) at 10 kt, around the southwestern periphery of a mid-level ridge centered over the southwestern United States. A break in the ridge should allow Marie to turn northwestward within the next 24 hours and maintain that motion over the next several days. By day 5, an approaching upper-level trough moving across the eastern Pacific Ocean should turn Marie more toward the north-northwest. There is still more noticeable spread in the guidance at days 4 and 5, likely related to differences in the amplitude of the upper-level trough. It is worth noting that the GFS depicts a deeper upper trough, and thus a more drastic northerly turn, than the rest of the global models. Overall, the NHC forecast was again slowed down a bit and shifted slightly to the right to align better with the latest TVCE multi-model consensus and HCCA aids. Marie is expected to remain in a low-shear environment with sea surface temperatures of 26 degrees Celsius for the next 18-24 hours. Although slight additional strengthening cannot be ruled out, the storm is running out of time before environmental conditions become more hostile. After 24 hours, increasing deep-layer southwesterly shear and cooler waters should support a steady weakening trend through the rest of the forecast period. Marie is expected to fall below hurricane strength by 60 hours and become a tropical depression by day 5. The latest NHC intensity forecast shows a slightly faster weakening trend and remains very close to the IVCN consensus and the HCCA aid.
