I'm gonna go ahead and explain what the steering maps are for and how they should be used.. there are 6 maps of steering, each of those are different. 1. Steering Layer 700-850 for TC MSLP of 1000-1010 This would be steering currents for something like Noel or Barry or basically a Tropical Storm/ Minimal Hurricane.
1000- 1010 means the low pressure of the storm (example.. 1002 milibars)
2. Steering Layer 500-850 for TC MSLP of 990-999
This trend continues to go down unitl you reach a category 4-5 magnitude which is 940 or below.
Steering maps can be helpful, especially with times like these lol If you really want to know when Noel is going to recurve, do the math.. go to the first steering map and click on -3 hours 8 times which equals 24 hours ago. Look where the ridge is at and then go foward 3 hours 8 times. the ridge is moving, and should allow Noel to recurve in 18-24 hours from now. I hope this explains the whole westward movement.
