SPORADIC GALE FORCE WINDS POSSIBLE THROUGH 1 AM
Recent observations across lower portions of the Chesapeake Bay continue to show some gale force winds up to around 35 knots. These northwesterly winds should remain gusty at times over the next few hours. Mariners should be prepared for an increase in winds and waves. Those in small craft should consider moving to safe harbor.
EMBEDDED THUNDERSTORMS POSSIBLE THIS EVENING THROUGH EARLY FRIDAY MORNING
An atmospheric river will move into the region this evening and isolated embedded thunderstorms may accompany rounds of heavy rainfall. Any thunderstorm that occurs will be capable of producing hazardous conditions including locally gusty/erratic winds, rough seas, lightning, and reduced visibility.
DANGEROUS ICE CONDITIONS POSSIBLE ON LAKE ERIE THIS MORNING THROUGH TONIGHT
West winds will increase to 20 to 30 knots in the central and eastern basins of Lake Erie through most of tonight. These strong west winds will cause ice to shift to the east and potentially close shipping lanes.
DANGEROUS ICE CONDITIONS POSSIBLE IN THE WESTERN BASIN OF LAKE ERIE THROUGH THIS EVENING
West winds will increase to 20 to 25 knots in the western basin through this evening. These strong offshore winds could cause ice floes to break off from the lakeshore. If this occurs, anyone caught on the ice would become stranded. It is strongly advised to stay off of the ice through this evening. As a notice to mariners, the strong west winds may cause ice to shift to the east and potentially close shipping lanes.
Chance of Thunderstorms and Dangerous Ocean Conditions from through this evening for the Coastal Waters of Southern California
A strong low pressure system with an associated cold front will bring strong winds, large seas, and the potential for strong thunderstorms to the coastal waters beginning this morning. Any thunderstorm that forms will be capable of producing erratic, locally gale force winds and rough seas, dangerous lightning, heavy rainfall with reduced visibility, and waterspouts. The cold front passage will bring widespread southwest gale force winds for the northern coastal waters. Local gale force gusts are expected over the remaining waters prior to the frontal passage. Seas will also increase significantly, ranging from 10 to 18 feet for the waters off the Central Coast, and 6 to 10 feet for the inner waters south of Point Conception. Conditions will be exceptionally dangerous for all but the largest vessels. Lightning, heavy rain, gales, low visibility and steep, choppy seas will make navigation difficult, and may damage and or capsize vessels. Boaters are strongly advised to remain in safe harbor.
