CMC Atlantic MSLP Description
The Canadian Meteorological Center (CMC) produces a global computerized weather forecast model twice daily. The CMC model is global, as opposed to, the GFDL and WRF models which are regional models centered over North America. The CMC model is run through 240 hours.

The graphic above shows the barometric pressure field in the western Atlantic, Gulf and Caribbean. Lower pressures are indicated in dark blue. Higher pressures are indicated in red. Hurricanes and tropical storms, as well as non-tropical low-pressure areas, are associated with low pressure (blue). The black lines are isobars (lines of equal pressure). The closer the lines are to each other, the stronger the winds. The gray arrows are wind vectors showing speed and direction. The wind arrows point towards the direction the wind is blowing towards and the length of the arrow indicates speed. The longer the arrow is, the stronger the speed.

Remember that these are mathematical models with varying initial assumptions. Thus, different models produce different final results. They do not necessarily reflect the "official" hurricane track issued by the National Hurricane Center. Forecasters review all of the model data but use their own experience and scientific expertise to arrive at a final forecast.
