Potential Tropical Storm Tammy’s Impact
Meteorologists specializing in hurricanes are closely monitoring a cluster of showers and thunderstorms currently situated in the central Atlantic. There is a growing possibility that this weather disturbance may evolve into the next officially named tropical system within the Atlantic basin.
This particular tropical wave, officially designated as Invest 94L by the National Hurricane Center (NHC), is expected to continue its westward movement across the central Atlantic. Over the course of this week, experts in meteorology anticipate that this disturbance will become progressively more organized. As a result, there is a significant likelihood of it developing into a tropical system sometime between October 18th and 20th.
Should this weather phenomenon mature into a tropical storm, it would acquire the name Tammy, marking the 19th named storm of the season. With only two names remaining on the predetermined seasonal list after that, the World Meteorological Organization (WMO) will step in to provide names for any further organized systems.
As for the path of this potential tropical system, the prevailing steering flow in the Atlantic is predicted to remain stable through the middle of the week. This will direct the system westward, following a trajectory akin to that of former Tropical Storm Sean just last week. Towards the end of the week and into the weekend, an area of high pressure in the northern Atlantic will play a pivotal role in influencing the direction of the storm. Depending on the precise location of this high-pressure area, the storm may either persist on a southerly path towards the Lesser Antilles or veer northward and stay over the ocean.
It’s worth noting that this system is already positioned further south than Sean was, which raises the possibility of impacts on the eastern Caribbean, something that Sean was unable to achieve. If the system maintains its structure as it crosses the Atlantic, it could bring effects such as heavy rainfall and turbulent sea conditions to the Lesser Antilles later in the week and during the weekend.
The 2023 Atlantic hurricane season has been notably active, with 18 named storms thus far. Approximately six weeks remain in the official hurricane season, which concludes on November 30th. This season has exceeded the historical average in terms of named storms. In a typical hurricane season, only 14 named storms form across the basin.
Out of the 18 named storms this season, six have intensified into hurricanes, with three reaching major hurricane status, defined as Category 3 or higher, featuring sustained winds of at least 111 mph.
The most potent hurricane in this season has been Hurricane Lee, which reached Category 5 status, boasting winds of 165 mph, while situated over the central Atlantic. On September 16th, Lee made landfall as a tropical wind and rainstorm in western Nova Scotia, bringing heavy rainfall and damaging winds to portions of New England and Atlantic Canada.
