The final storm of the year was a strong depression in the southern Caribbean Sea. This system was active for less than two days but may have briefly attained tropical storm intensity as it made landfall in southern Nicaragua. The first named storm formed out of the interaction between tropical wave and a mid-level tropospheric trough northeast of the Bahamas in late-June. A well-defined circulation became apparent by June 30 and satellite images depicted cyclonic banding features. The following day, the system intensified into a tropical depression and shortly thereafter became a tropical storm as reconnaissance aircraft recorded gale-force winds. An area of high pressure to the east of Alice steered the storm generally to the north. Decreasing wind shear allowed the storm to become increasingly organized and a well-defined eye developed by July 3. By this time, reconnaissance had determined that the storm had intensified into a hurricane, with maximum winds reaching 80 mph (130 km/h). On July 4, the storm reached its peak intensity with winds of 90 mph (150 km/h) and a barometric pressure of 986 mbar (hPa; 29.11 inHg), as the eastern portion of the eyewall brushed Bermuda. After passing the island, Alice began to accelerate in response to a mid-level trough over the eastern United States and weakened. By July 6, winds head decreased below hurricane intensity as the storm neared Atlantic Canada. Later that day, Alice made landfall in eastern Newfoundland with winds of 60 mph (95 km/h) before transitioning into an extratropical cyclone. During its passage of Bermuda, Alice produced sustained winds up to 75 mph (120 km/h) and gusts to 87 mph (140 km/h). No major damage was recorded on the island, though the winds blew down a few trees and powerlines. The heavy rainfall, peaking at , ended a three-month drought in Bermuda. Although Alice tracked through Atlantic Canada, no impact was recorded. During late July, an upper-level low, with a non-tropical cold core, formed near Cape Hatteras, North Carolina and tracked southward. Gradually, the circulation lowered to the surface and developed subtropical characteristics. On July 31, the system attained gale-force winds off the Mid-Atlantic coast and was named Alfa, the first name from the list of subtropical storm names for the 1973 season. Tracking north-northeast, the system intensified very little as it paralleled the coastline.
