Hurricane Eta Discussion Number  10
NWS National Hurricane Center Miami FL       AL292020
1000 PM EST Mon Nov 02 2020

An Air Force Reserve reconnaissance aircraft has found that Eta has 
explosively deepened into a strong category 4 hurricane with maximum 
sustained winds of 130 kt and a minimum central pressure of 927 mb. 
Eta has maintained a small 10-nmi-wide eye that is evident in 
satellite imagery and on the San Andreas, Colombia, weather radar. 
The radar data also suggest that concentric eyewalls may be forming, 
which would be an indication of the onset of an eyewall replacement 
cycle (ERC) and a capping of Eta's intensity and also an end to the 
rapid intensification cycle of the past 36 hours. The initial 
intensity of 130 kt kt is based on 700-mb flight-level winds of 137 
kt and SFMR surface winds of 130 kt. Some additional strengthening 
is expected, and Eta could become a category 5 hurricane before 
landfall occurs. After landfall, Eta should quickly weaken while it 
moves over the mountainous terrain of Central America.
