Post-Tropical Cyclone Hanna
Post-Tropical Cyclone Hanna has become a remnant low pressure area located about 1230 miles east of Bermuda and about 980 miles west-southwest of the Azores. The cyclone is moving east at 5 mph with maximum sustained winds of 35 mph. No coastal watches or warnings are in effect as the system poses no threat to land. This is the last advisory by the National Hurricane Center on Hanna.
Tropical Storm Hanna, which formed far out in the Atlantic, has been a topic of significant speculation and monitoring by meteorologists. Initially, the storm appeared to be on a trajectory that could affect parts of the Azores and Bermuda, raising concerns about potential impacts to these regions. However, recent updates have indicated that Hanna is expected to weaken as it continues its path across the Atlantic, reducing the likelihood of severe weather conditions in these areas. As a result, although initial forecasts prompted caution, the storm's decreasing strength is offering some relief to those in its potential path.
Despite earlier concerns, Tropical Storm Hanna is now forecasted to significantly diminish in intensity by nightfall, according to the National Hurricane Center. This downturn in strength means that, while Hanna once posed a potential threat, it is now likely to fall short of causing serious damage or disruption. Meanwhile, another weather system, once classified as Tropical Storm Fay, has transitioned into a post-tropical state, further indicating a calming of systems in the Atlantic. The weakening of these storms underscores the unpredictable nature of tropical systems but also offers a reprieve from what could have been more severe weather situations this hurricane season.

A tropical wave in the western Atlantic is moving westward with associated scattered moderate to isolated strong convection. The monsoon trough and Intertropical Convergence Zone (ITCZ) in the Atlantic are causing scattered moderate convection in the region between Guyana and Venezuela.
The Gulf of America is experiencing showers and thunderstorms, especially over the SE Gulf, due to deep-layer troughing. High pressure over the eastern U.S. is causing moderate to fresh easterly winds in the western Gulf. Changes in wind patterns are expected as a frontal boundary approaches, potentially bringing increased winds and seas in the western Gulf by the weekend.
In the Caribbean Sea, the East Pacific monsoon trough is causing strong convection in the SW part of the region. High pressure north of the area is maintaining moderate to fresh easterly trade winds, with strong winds off northern Colombia. The pressure gradient is expected to weaken due to an approaching frontal boundary, leading to moderate to locally fresh winds across the Caribbean.
The Atlantic Ocean is affected by deep-layer troughing resulting in scattered moderate convection near the Bahamas towards Cuba. High pressure is causing moderate to fresh easterly winds south of 25N. Remnants of Post-Tropical Cyclone Fay might move west of 55W and dissipate later in the week. A frontal boundary may increase winds and seas off NE Florida early next week.
The National Oceanic and Atmospheric Administration (NOAA) has forecasted an above-normal Atlantic hurricane season for 2025.
Named Storms: 8 to 14
Hurricanes: 3 to 6
Major Hurricanes (Category 3 or higher): 1 to 3
Accumulate Cyclone Energy (ACE): 95% to 180% of the median
Primary Influencing Factor: Developing El Niño conditions expected to suppress Atlantic storm activity
This forecast indicates:
Despite the lower forecast, NOAA emphasizes that it only takes one hurricane making landfall to create a major disaster, and residents in hurricane-prone areas should still prepare as usual for the season.

2020 - 30 named storms, 14 hurricanes
Hurricane Katrina (2005) - $125 billion
Harvey (2017) - $125 billion
Hurricane Patricia (2015) - 215 mph (345 km/h)
Hurricane Allen (1980) - 190 mph (305 km/h)
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating system that classifies hurricanes based on their sustained wind speeds and the potential damage they can cause. It helps communicate the intensity of hurricanes and the likely impacts on structures and environments. The scale does not account for factors like storm surge or rainfall, focusing only on wind speeds.
Watching the Tropics was originally built as a personal storm tracker with only the most important charts for the Atlantic hurricane basin. Numerous sites are available for tracking hurricanes, but Watching the Tropics minimizes extra "noise" and shows only what you need.

"Watching the tropics" refers to monitoring tropical weather systems, such as tropical depressions, tropical storms, and hurricanes, in regions close to the equator. Meteorologists and weather enthusiasts often use this phrase during hurricane season to indicate that they're keeping an eye on developing weather systems that could potentially strengthen and impact areas like the Caribbean, Gulf of Mexico, and Atlantic Ocean.
Websites, news outlets, or weather services also use "Tropics Watch" to keep the public informed about the latest developments in the tropics, especially during peak hurricane season.
An "invest" refers to an area of disturbed weather that meteorologists are investigating for potential tropical development. The term "invest" is short for "investigation area."
When an area is designated as an invest, it is given a number (between 90 and 99) followed by the letter "L" for systems in the North Atlantic or "E" for systems in the Eastern Pacific. For example, "Invest 91L" would refer to the 91st area of interest in the Atlantic basin for that season.
The designation of an invest allows meteorologists to focus their resources on a specific area, utilize specialized forecasting models, and issue updates as needed.
A tropical depression is a type of tropical cyclone with maximum sustained winds of less than 39 mph (34 knots or 63 km/h).

It's the first stage of development in the tropical cyclone classification used by the National Hurricane Center, followed by tropical storm and then hurricane.
