Central America Wave Heights

The FNMOC SWELL HEIGHTS Forecast is another version of the THE SIGNIFICANT SWELL HEIGHT FORECAST charts, which shows us a full 7-day forecast of SWELL/SEA HEIGHTS With other than slightly different tweaking to get a better view of a smaller area the FNMOC model works the same way the bigger models work...more information


Central America Wave Periods

The FNMOC SWELL PERIOD Forecast is a smaller, more focused version of the swell-period forecast charts that you can see globally, by ocean, regionally, and sub-regionally. They track swell in swell period form as the energy moves away from the storm source. This tracking, particularly at this tighter resolution allows you to see how the incoming swell moves through the region…and how in some of the more cramped areas it will be shadowed or refracted...more information


Central America Precipitation

Another tighter resolution version of the sea-level-pressure chart…still gives you the 7-day forecast but since the FNMOC charts we are normally using, are targeted at the tropical regions, it gives us more of a heads up on potential tropical storms. If we see a tightly wound ball of low-pressure, at some intense rainfall, thunderstorms, which generally indicate we could see some deeper convection and potentially a tropical storm forming in the region...more information


Central America Winds

The FNMOC wind-stream forecast model shows the surface winds, and even pulls out areas where the winds get intense by using color blobs and wind flow with those same directional areas. The main difference is that the COAMPS uses a grid that creates a point every 10-meters while the FNMOC model has grid points as far as 10-15 miles apart…it makes for less “dialed in” focus that you see on the COAMPS ,but it saves a lot of time crunching the numbers, which allow is to cover a bigger region...more information


Central America Sheer

The 180-hour Shear forecast chart is for extreme hurricane junkies and pilots that don’t like their planes torn in half. There is so much happening on this chart that it almost gives you a seizure the first time you look at it…but once you start to understand the color scheme. In this chart, blue stands for heavy shear, which means the winds in the layers are blowing in opposite directions. Yellow is for medium shear, so winds aren’t totally blowing against each other but they aren’t helping either. Green means are all layers are blowing the same direction and there is little no shear…these are the ideal conditions for tropical storm/hurricane formation...more information
