What are spaghetti models?
What are spaghetti models? Spaghetti models (also called spaghetti plots) is the nickname given to the computer models that show potential tropical cyclone paths. When shown together, the individual model tracks can somewhat resemble strands of spaghetti.
Why would I want to view spaghetti models? In short, it gives you a way to see where a tropical storm or hurricane may head. It can also give insight into whether the models are in agreement on the path of the storm (for instance, all models show Florida in the path of a hurricane) or if there is a wide differing opinion on where the storm may go. For instance, in the case of Tropical Storm Debby, the original NHC storm path had her going straight west to Texas, but if you viewed the spaghetti models at that time, you would have had a glimpse into just how uncertain Debby's path was. Debby's spaghetti models had her making landfall from anywhere from Texas to Florida to everywhere in between.
Spaghetti models are also useful in the case of a developing storm system that has not officially become a tropical depression or a tropical storm, meaning that no agency has released an official path. In these instances, spaghetti models can serve to give you an early heads up as to where a future tropical storm or hurricane may head.
However, once a tropical disturbance has officially become a tropical cyclone, different government agencies (e.g. the National Hurricane Center for the Eastern Pacific and Atlantic basins) release an official best guess path based on their analysis of the different model data and other factors. These forecasts should be used for official planning, though the spaghetti plots can still be quite useful for seeing how confident all of the models are (e.g., in the case of Debby listed above).

FAQs
In 2021, the GFS was the most accurate model followed by the European. Overall, the official forecast was the most accurate in terms of forecast track accuracy.
What are spaghetti models used to predict? ›
Spaghetti models are a type of model used to predict the future path of a tropical cyclone. Patrick J.
How often are spaghetti models updated? ›
The center's consensus models are put together based on model performance over the previous hurricane season. Some of the bigger global models take so long to run that the information they provide must be adjusted forward based on a storm's current position when the center makes its forecast update every six hours.
What do spaghetti models refer to? ›
The term spaghetti models refers to a visual comparison of multiple forecast models using lines that come out of a center of low pressure in the atmosphere. Each of the lines represents a different forecast model's idea of where it thinks the center of a developing storm system will go.
Is euro or GFS more accurate for hurricanes? ›
The European model had the lowest probability of correctly making a genesis forecast – near 20% – but had the fewest false alarms. The GFS correctly made genesis forecasts 20 – 25% of the time but had more false alarms.
Have hurricane spaghetti models been wrong? ›
Spaghetti models provide a range of possible paths for a hurricane based on various weather models. Their accuracy can vary, but they are a valuable tool for tracking storms. The more closely the paths align, the more confident meteorologists are in the forecast.
Why do weather forecasters use spaghetti models? ›
Spaghetti models show where a tropical system may go. When clustered together, forecast confidence is high. But spaghetti plots do not show where impacts will occur.
Why is it called spaghetti model? ›
A spaghetti plot (also known as a spaghetti chart, spaghetti diagram, or spaghetti model) is a method of viewing data to visualize possible flows through systems. Flows depicted in this manner appear like noodles, hence the coining of this term.
What is the most reliable hurricane tracker? ›
HMON: The HMON is a refurbishing of an older American hurricane model, and sometimes wanders off on its own with odd predictions. Despite this, HMON actually led the pack for track forecasting in 2022 between two and four days' lead time, and has outperformed the newer HWRF in average track errors since 2020.
What hurricane model does NOAA use? ›
The Hurricane Analysis and Forecast System (HAFS) is NOAA's next-generation numerical model and data assimilation system developed within the framework of the Uniform Forecast System (UFS).
This year, NOAA predicts a very high likelihood (85% chance) of an above-normal Atlantic hurricane season (2), with 17-25 named storms (average is 14), 8-13 hurricanes (average is 7), and 4-7 major hurricanes (average is 3) (3).
Which spaghetti model is more accurate? ›
The European Center for Medium-Range Weather Forecasting Model (ECMWF) is widely considered the best for predicting global weather patterns and has been beating the other models in terms of accuracy, but looking to rely on one model over another isn't the correct approach, said National Weather Service Meteorologist ...
How accurate are hurricane season predictions? ›
NOAA does not tend to over-hype the chance for hurricanes. "Over the past five years, NOAA forecasts have been very accurate," WRAL meteorologist Kat Campbell said. Where they have not been right on, they have forecast fewer named storms than what actually happened.
Can a hurricane path be predicted? ›
With satellites, ships, land sensors, and weather balloons flown into the cyclone, forecasters measure storm surge, sea surface temperature, size, shape, and wind speed. From this data, a hurricane prediction can be made, such as the storm's expected path and severity.
Which hurricane model is historically most accurate? ›
Experts generally agree the European model has an edge over the GFS, Rood said. Both are modeled from equations performed by high-powered computers. The GFS and the European both are medium-range forecasting models and can forecast fairly far into the future.
Which weather model is most accurate? ›
Global models with worldwide weather forecasts
These models are all generally fairly accurate in predicting large scale patterns/features, but all will become less accurate through time. The ECMWF is generally considered to be the most accurate global model, with the US's GFS slightly behind.
What is the difference between GFS and Ecmwf hurricanes? ›
Let's summarize the main differences between both leading weather forecasting models: Resolution: GFS runs at a lower resolution than the ECMWF model. The grid points in the GFS model are located farther apart (every 13 kilometers) than the ECMWF model (every 9 kilometers).
Which model was most accurate for Hurricane Ian? ›
But the American model was the best at getting Ian's strength right, she said. University of Albany meteorology professor Brian Tang said he calculated the American model's average track error during Ian at 325 miles (520 kilometers) five-days out, while the European model was closer to 220 miles (350 kilometers).
