Tropical Eta

You're surprised the pressure of 927 mb is that "high"? This is the strongest of the entire season and is lower than even most of, if not all of the HWRF runs. How low did you really expect?

The presentation definitely has a sub-900 look. Here's a comparison of Patricia and Wilma...it looks even more organized.

Maybe Eta is a smaller/more compact storm than the others? Wouldn't that mean a similar look but not as insanely low pressure?

Background surrounding pressures may be higher in this case (corrected). If higher, then a similar look and similar winds could mean not as low pressure.

We need to keep in mind just how low 927 mb is and how .rare sub 900 is. Besides, this may get even stronger and they missed the eye apparently??

Wouldn't compact storms more closely relate to windspeeds since the pressure gradient would be tighter with these small compact storms?

I think it is the opposite. More compact/smaller would mean you can get the same winds with higher pressure. OTOH, huge storms sometimes have very low pressure but not very high winds.

So, do you know what the radius of tropical storm force as well as H force winds was with Wilma and Patricia and how they compare to Eta?

Well it doesn't change anything for poor Central America but there were plenty of people expecting way lower

Pretty much what I'm trying to say....the winds they found weren't as impressive as I expected either considering the compactness of the storm...I guess it could be possible the storm's winds and central pressure hasn't caught up to it's own presentation.
 
Probably missed the center a tad bit had 17 knts on the eye drop so maybe 923/924mb is closer to the pressure....tough to hit the center when the eye is so small they fly through it in less than a minute....

The most interesting part is how strong is the winds in the NE quadrant?
 
Kind of surprised that the pressure wasn't lower given the presentation but it doesn't change the situation. Just bad for the people in Nicaragua and Honduras.
