Norman has rapidly strengthened during the past 12 to 24 hours,
with the development of a well-defined 20-nmi-wide eye and a thick
ring of cold cloud tops of -70 to -85C. Dvorak constraints have
limited the amount of increase in the subjective and objective final
T-numbers, but the most recent raw data T-numbers are between T6.5
and T7.2, which yields an initial intensity estimate of 130 kt.
Norman's intensity has increased an estimated 70 kt from 1200 UTC
yesterday morning to 1200 UTC this morning- the fastest in the
basin since Patricia in 2015. Norman has become the 5th category 4
hurricane in the eastern Pacific in 2018 and is also the strongest
hurricane in the basin so far this season.
