Hurricane Oscar 2018

Last Modified:

Satellite images and tracking maps of Category 2 Hurricane Oscar 2018, October 26 - November 4. Max wind speed 110mph.

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 nautical miles 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 knots for the next 48 hours, then gradually weaken as the baroclinic energy wanes, with dissipation occurring between 96-120 hours over the far northeastern Atlantic.

The initial motion is now 030/30 knots. 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
