SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 AM AST (0600 UTC), the center of Tropical Depression Gaston was located near latitude 40.2 North, longitude 27.9 West. Gaston is moving toward the east-northeast near 16 mph (26 km/h). An east- northeastward and then northeastward motion with an increase in forward speed is expected during the next 12 to 24 hours. On the forecast track, the center of Gaston will continue to move way from the Azores. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is expected, and Gaston is forecast to become a remnant low this morning. The remnant low should dissipate by Sunday morning. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Gaston are affecting the Azores, and should continue today. These swells are could cause life- threatening surf and rip current conditions. For more information, please consult products from your local weather office.

Tropical Depression EIGHT Forecast Discussion Number 15
2016-09-01 04:44:21| National Hurricane Center (Atlantic)
Issued at 1100 PM EDT WED AUG 31 2016 000 WTNT43 KNHC 010244 TCDAT3 TROPICAL DEPRESSION EIGHT DISCUSSION NUMBER 15 NWS NATIONAL HURRICANE CENTER MIAMI FL AL082016 1100 PM EDT WED AUG 31 2016 Deep convection is becoming increasingly dislocated from the center of the tropical depression because of the strong westerly vertical shear. Dvorak classifications from SAB and TAFB continue to drop as the convection becomes less organized. The initial intensity remains 25 kt. The tropical depression should not be long for this world. Last- light visible imagery suggests that the center may be becoming diffuse. The deep convection may soon either dissipate or be located far from the center. The system may shortly become entangled in a frontal boundary. If the center is no longer well defined, if there is no associated organized deep convection, or if the cyclone becomes frontal, then the system will no longer be a tropical cyclone. One or more of these options should occur within about a day, if not sooner. In about two days, the post-tropical cyclone is likely to be absorbed in a separate extratropical low. The depression is moving toward the east-northeast at about 14 kt, as it is being swept up by the southwesterlies ahead of a mid-latitude shortwave trough. The system should accelerate in the same direction until dissipation. The track is based upon the consensus of the reliable global models and is nearly the same as that from the previous advisory.
