At 500 PM AST (2100 UTC), the center of Tropical Depression Omar was located near latitude 36.1 North, longitude 65.7 West. The depression is moving toward the east near 14 mph (22 km/h), and this general motion is expected to continue through Friday. A turn toward the eastnortheast with some reduction in forward speed is forecast on Saturday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Further weakening is forecast and Omar is likely to become a remnant low Thursday with dissipation by Saturday night. The estimated minimum central pressure is 1005 mb (29.68 inches).

Conventional satellite imagery shows that Omar's cloud pattern is rapidly deteriorating, and the surface circulation center has become quite ill-defined. This morning's METOP-A/B scatterometer passes revealed only a few 33 kt winds well to the southeast of the center and it's reasonable to determine that those winds are no longer present. Therefore, the initial intensity is lowered to 30 kt for this advisory and is further supported by the subjective satellite intensity T-numbers from TAFB and SAB. The latest global model runs agree with the depression degenerating to a remnant low in 24 hours, or less, and the NHC intensity forecast follows suit. Dissipation of the remnant low should occur no later than Saturday evening.

Omar's initial motion is estimated to be due east, or 090/13 kt, within the mid-latitude westerlies north of a subtropical ridge stretching east to west over the central Atlantic. Omar should continue moving eastward through Friday, although a couple of the global models are showing a track a bit more east-southeastward. Around the 60 hour period, the remnant low is expected to reduce in forward speed, and turn toward the east-northeast in response to an approaching baroclinic system entering the northwest Atlantic. The NHC forecast is nudged just a little to the right of the previous one, and lies close to the HCCA and TVCA consensus models.

A brief and small burst of convection developed near the center of Omar early this evening, only to be quickly sheared well to the southeast of the exposed low-level center. Any new convection that developed during the day has been smaller in coverage and shorter lived, and this trend is expected to continue. The initial intensity is being held at 30 kt based on a recent ASCAT overpass showing several peak 30-kt wind vectors in the southern semicircle. There is no change to the intensity forecast reasoning. Ongoing wind shear of 40-50 kt should not allow any developing convection to persist near Omar's center, and the depression should degenerate to a remnant low sometime on Thursday. This scenario is in agreement with the global model forecasts. A few days from now, the remnant low should dissipate as it becomes absorbed by a larger approaching mid-latitude frontal system. Omar continues to move east at around 13 kt, to the north of a subtropical ridge. An east or just south-of-east motion is forecast through Friday. After that time, the remnants of Omar should turn east-northeastward to northeastward ahead of the approaching mid-latitude frontal system. The latest NHC track forecast is very close to the previous one and is also near the various consensus aids.
