Tropical storm weather forecast maps released by The Weather Company are highlighting current systems, potential development zones and important atmospheric conditions across the Pacific and Atlantic basins. The latest tracker was updated on August 24, 2026, and includes information for residents, travelers and emergency planners following the 2026 hurricane season.
The maps show where tropical systems are located now, where forecasters are watching for development and how conditions could evolve. Among the Pacific systems referenced in the update are Lala and Iselle, along with other areas under observation. However, the available report does not provide specific storm strength, landfall projections or impact forecasts for those systems.
Powerful Tropical Storm Weather Forecast Maps Cover Two Basins
The Pacific section begins with satellite imagery showing current tropical activity and areas of interest. Forecast cones of uncertainty provide a visual guide to possible storm movement, while storm-track maps show projected paths. These cones are not exact predictions of a storm’s center; they represent a range of possible outcomes and can change as new data becomes available.
Additional Pacific products include current radar, forecast rainfall and spaghetti-model graphics. Rainfall maps can be especially important because tropical systems may produce flooding far from the strongest winds. Spaghetti models, meanwhile, display multiple computer model projections and help illustrate the uncertainty surrounding a storm’s future movement.
- Current systems: Satellite imagery identifies tropical activity and monitored areas.
- Forecast tracks: Cones and model projections show possible movement.
- Rainfall threats: Heavy precipitation may create flooding concerns.
- Radar information: Current weather patterns can be tracked as storms develop.
Critical Atlantic Conditions Include Wind Shear and Dry Air
The Atlantic maps focus on several environmental factors that influence tropical cyclone development. Sea surface temperatures are closely watched because warm ocean water can provide energy to thunderstorms and developing storms. Warmer waters do not guarantee formation, but they are one of several ingredients forecasters examine.
Wind shear is another major factor. The Weather Company describes it as a difference in wind speed or direction with height. Strong wind shear, shown in purple on the map, can disrupt the circulation of tropical storms and hurricanes. It may weaken existing systems or make it harder for new disturbances to organize.
Dry, dusty air is also shown across parts of the Atlantic. During hurricane season, air containing dust from Africa’s Sahara Desert can move westward across the basin. This dry air tends to suppress thunderstorms, which are essential building blocks for tropical cyclones. Areas shaded brown are therefore generally less favorable for development at the time of analysis.
Season Activity Measured Through Accumulated Cyclone Energy
The tracker also compares activity so far this season with historical averages. One key measurement is Accumulated Cyclone Energy, commonly called ACE. This metric estimates the total energy produced by named tropical storms and hurricanes over a period, taking into account both their strength and how long they last.
ACE helps meteorologists assess whether a season has been unusually active, near average or quieter than normal. The report includes an ACE comparison dated August 17, 2026, using data credited to Phil Klotzbach of Colorado State University. A single metric cannot describe every threat, but it offers useful context for evaluating the broader season.
What Residents Should Watch Next
People living near coastlines or in areas vulnerable to flooding should continue monitoring official forecasts and emergency alerts. Conditions can change quickly when tropical disturbances encounter warmer water, weaker wind shear or more humid air. Even a system that does not become a hurricane can bring dangerous rainfall, gusty winds, rough seas and power disruptions.
The maps are designed to help the public understand storm behavior and possible hazards, but they should not replace guidance from emergency management agencies. Residents should review evacuation routes, check emergency supplies and know how to receive local warnings before conditions deteriorate.
The Weather Company’s latest hurricane season tracker provides a broad overview of activity in both basins. With Lala, Iselle and other monitored areas appearing in the Pacific discussion, forecasters will continue watching satellite trends, ocean temperatures, atmospheric moisture and computer-model guidance for signs of strengthening or weakening.
Frequently Asked Questions
What does a tropical storm forecast cone show?
A forecast cone shows the probable range of a storm’s center over a specific period. It does not show the full area that could experience rain, wind, flooding or storm surge.
Why is wind shear important during hurricane season?
Strong wind shear can tilt or disrupt a tropical cyclone’s circulation. This often makes it more difficult for thunderstorms to remain organized and for a storm to strengthen.
How does Saharan dust affect Atlantic storms?
Saharan dust often carries dry air across the Atlantic. That dry air can reduce thunderstorm activity and create an unfavorable environment for tropical storm formation.
What is Accumulated Cyclone Energy?
Accumulated Cyclone Energy, or ACE, measures the combined energy of tropical storms and hurricanes by considering their wind strength and duration.
Where should residents get emergency updates?
Residents should rely on local emergency officials and recognized weather authorities for evacuation instructions, watches, warnings and safety information.
