I saw a recent report that the hurricane hunter planes are finding lower pressures.

They report a “stadium effect”.

Hurricane hunters fly into the eerily calm eye of Irma (video at link)

Fierce rains and 185-mph winds pelted the Virgin Islands and Puerto Rico on Wednesday afternoon as Hurricane Irma continued pushing northwest on its relentless path across the Atlantic Ocean.

While the Category 5 storm writhed below, a crew with the National Oceanic and Atmospheric Administration (NOAA) took to the air on Tuesday to survey the hurricane from within.

Calm prevailed as the crew reached the inner circle of the storm. Inside the eye, the immense pressure forces the cloud wall to curve upwards in a phenomenon known as the “stadium effect.”
