  • AccuWeather – Features forecast articles, interactive maps, radar, model data, and videos for tropical storm/hurricane tracking.
  • – An interactive weather map that integrates real-time hurricane tracking, forecasts, radar, satellite maps, and model ensemble data.

These resources provide live updating tropical cyclone positions, forecasts, and surrounding environmental data as storms progress. Next, we’ll explore the key types of real-time hurricane tracking maps available online.

Interactive Tracking Maps for Real-Time Monitoring

When a storm first develops and is tracked by the NHC, they provide forecast data and issue advisory packages 4-5 times per day. To visualize this data, various interactive map options are available:

NHC Tracking Map

  • The official NHC tracking map interface shows the present position and past track history of an active storm based on satellite, radar, and reconnaissance aircraft data.
  • It plots the tropical cyclone’s position every 6 hours with a dot, including the estimated 34, 50, and 64kt wind radii.
  • Forecast projections also show the expected track over the next 5 days with Potential Storm Surge Flooding Map areas.

Spaghetti Models

  • Spaghetti plots overlay many different forecast model solutions for a storm’s expected track extending 3-5 days out.
  • Viewing the “spaghetti” of model lines allows you to look for consensus or more outlier solutions.
  • Tropical Tidbits has an excellent spaghetti model interface to compare forecasts.

Satellite Imagery

  • Continuously updated satellite maps allow you to visually inspect the structure and organization of a tropical cyclone in real-time:
    • Visible satellite – View storm features during daytime hours
    • Infrared – Measure cloud top temperatures at night
    • Water vapor – Locate circulation center and dry air intrusion
    • Floater loop – Focuses on the storm itself as it moves
  • NOAA offers many real-time tropical satellite images

Radar Maps

  • As a tropical system gets closer to land, use high resolution radar maps to analyze the inner core and rainfall structure:
    • Intensity changes
    • Rotation
    • Banding features
    • Tornado potential
  • RadarScope and have great radar interfaces.

Model Forecast Data

  • Beyond the tracking map, most computer forecast models also output various environmental fields surrounding the tropical cyclone:
    • Wind shear analysis
    • Sea surface temperatures
    • Mid-level moisture
    • Precipitable water values
    • And much more
  • Tropical Tidbits has an excellent collection of model analysis options.

By utilizing an assortment of these interactive real-time maps, you can monitor critical details on a storm’s present state and forecast evolution. Next we’ll break down important terminology and parameters to analyze.

Key Terms and Parameters to Analyze When Tracking

Monitoring the key data points and terminology listed below will give you important insights into a storm’s inner workings and forecast track/intensity:


  • Latitude/Longitude
  • Distance/Direction from a fixed point along the coast
  • Forward motion speed and direction

Maximum Sustained Winds

  • 1-min sustained wind speed in knots or mph
  • Indicates intensity per Saffir-Simpson Hurricane Wind Scale

Minimum Central Pressure

  • Measurement of atmospheric pressure at the center in millibars
  • Lower pressure indicates a more intense hurricane

Wind Radii

  • Radius of 34, 50, and 64kt winds from the center
  • Gives scope of tropical storm, hurricane force, and major hurricane force winds

Storm Structure

  • Eye diameter and characteristics
  • Eyewall convection, banding features
  • Symmetry or tilt of circulation

Environmental Influences

  • Vertical wind shear analysis
  • Ocean heat content and sea surface temps
  • Mid-level dry air intrusion

Model Forecasts

  • Track consensus and spread
  • Forward speed trends
  • Intensity changes
  • Timing of impacts

By familiarizing yourself with these parameters, you can better analyze model data, advisories, and radar/satellite maps when live tracking a hurricane. Next we’ll walk through a typical sequence when monitoring an active storm in real-time.

Step-by-Step Process for Live Hurricane Monitoring

When the first advisory is issued for a newly formed tropical cyclone, you can follow a sequence of steps to continually monitor the storm’s latest status. Here is a general process:

  1. Check the Latest Advisory Package
    • Gives location, intensity metrics, short-term motion
    • Has forecast thinking discussion from NHC forecasters
    • Issued every 6 hours for active storms
  2. Inspect the Interactive NHC Tracking Map
    • Plots latest position and wind radii
    • Shows forecast track and key watches/warnings
  3. Compare Spaghetti Model Plots
    • Look for consensus or outliers in forecast tracks
    • See how new model runs are trending
  4. Evaluate Satellite Imagery
    • Inspect structure and organization
    • Eye characteristics, symmetry
    • Convection trends, banding features
  5. Analyze Radar Maps Once Near Land
    • View inner core structure in high resolution
    • Look for intensification signatures
    • See bands, potential tornado threats
  6. Check Relevant Model Data Fields
    • Wind shear, moisture, ocean heat content
    • Steering currents, ridge influence
    • For insight into intensity changes
  7. Follow Expert Discussions
    • From NHC forecasters
    • Trusted meteorologists monitoring closely
  8. Consider Worst Case Scenarios
    • Focus on upper range intensity
    • Right-front quadrant dangers
    • Prepare for flooding and tornado threats

By sticking to this sequence of steps every time a new advisory package is released, you can stay on top of the very latest storm trends and threats. The more familiar you become with these tools, the better you will be able to analyze threats.

Next we will cover some best practices when using these tracking resources and interpreting the data.

Best Practices for Utilizing Live Tracking Resources

While interactive tracking maps make viewing storm data easy, it is also important to consider the limitations and have proper interpretation methods:

  • Location accuracy – Position estimates can vary between data sources up to 30 miles or more for weaker systems. Rely on the official NHC position.
  • Intensity changes – Wind speeds often fluctuate wildly from one advisory to the next. Focus on longer term trends.
  • Model consistency – No model is perfect, but look for consensus across guidance. The averages (“model consensus”) can be most reliable.
  • Future changes – The models cannot foresee rapid intensity changes or impacts once on landfall. So expect adjustments.
  • Leading edge – Focus on hazards along the storm’s future track and right-front quadrant for greatest impacts.
  • Land interaction – Once over land, model accuracy lowers substantially. Watch radar trends instead for the true impacts.
  • Local effects – Beyond the exact track, dangers like flooding and tornadoes can extend far from the center so consider worst-case scenarios.

By tempering expectations on accuracy and considering these best practices, you will have a much better experience using live hurricane tracking for real-time monitoring.

Now that we’ve covered the major tracking resources, parameters, and best practices let’s answer some common questions.

Frequently Asked Questions

What is the most accurate model for hurricane forecasting?

No single model is the most accurate every time, but the HFIP Corrected Consensus Forecast has historically shown the lowest average errors out to 5 days lead time. The Euro, GFS, and UKMET models tend to score well individually too according to NHC verification.

How often do hurricane forecasts change?

New advisory packages are issued every 6 hours with any updates to the storm’s position, intensity, and forecast. New forecast model runs also come in 4 times per day generally, with updates to the expected track so changes occur very frequently.

Can radar show a hurricane eye?

Yes, as the hurricane comes within range of land-based radar like NEXRAD (under 300 miles), its eye may be detected on radar imagery depending on beam angles and altitude. On dual polarization radar, the eye shows up as an expanding ring or arcs of low reflectivity surrounded by heavy precipitation in the eyewall.

What is a hurricane hunter aircraft?

Specially equipped hurricane hunter airplanes with NOAA and the Air Force Reserve fly directly into the core of hurricanes to provide critical real-time data on winds, pressure, temperatures that cannot yet be obtained from satellites at all altitudes. Dropsondes released from the planes feed this profile data on the storm environment into forecast models to improve accuracy.

How do meteorologists predict hurricane formation?

Meteorologists use satellite monitoring, computer model data, and Doppler radar analysis to identify areas of concern with potential tropical cyclone development. Factors like low wind shear, high moisture, organized thunderstorm activity, and warm ocean waters increase the chances a low pressure center will gradually organize into a tropical storm or hurricane over time.

What is the difference between a forecast cone and a forecast track line?

The forecast cone represents the probable track of just the storm center, with the historical average error showing it could fall anywhere inside the cone about 60-70% of the time. The actual forecast track line is the expected path of the center. Impacts can easily extend well outside the cone area since storms span hundreds of miles.

How do spaghetti models work?

Spaghetti plots overlay many independent computer forecast model solutions. They all have different calculations and assumptions in their algorithms. This allows meteorologists to look for clustering or consensus between the models, as well as outlier solutions, to assess the forecast uncertainty and confidence. More spaghetti leads often bring better agreement.


Accurately tracking hurricanes requires utilizing an array of real-time interactive maps, model guidance, radar imagery, and expert analysis. Fortunately, with the wealth of tracking resources now available online from official agencies and independent weather services, the data is at your fingertips.
