Hurricane Zeke is an extremely late storm in a very busy hurricane season. It has recently formed in the Caribbean, the 500-mb height at gridpoint 37 (relative to the storm) is 5400 m, the 500-mb height at gridpoint 3 is 5500 m, and the 1000-mb height at gridpoint 51 is –200 m (i.e., the surface pressure near the storm is well below 1000 mb).

a. Use the NHC 67 model (see Table 7.7) to forecast the westward component of its movement over the next 12 hours, if the storm has moved 80 n.mi. due westward in the previous 12 hours.

b. What would the NHC 67 forecast of the westward displacement be if, in the previous 12 hours the storm had moved 80 n.mi. westward and 30 n.mi. northward (i.e., Py = 30 n. mi.)?
