Still an impressive and powerful system at sunrise.

CMA now has Saola at 62 mps (223.2 kph) intensity / 915 hPa

[doomhaMwx]

55-60 dBZ reflectivity values and at quite a distance too (since this is from Taiwan radar) just really show how intense Saola's eyewall is.

The Atlantic is stealing Saola’s thunder

[doomhaMwx]

Although satellite presentation remains impressive, Saola has likely peaked as the latest SSMIS pass already shows a degradation of the internal structure with tell-tale signs of an impending EWRC.

[Kingarabian]

Not sure how this was never assessed cat.5.

[xtyphooncyclonex]

Quite a powerful looking 130-knot category 4 typhoon for sure.



CMG definitely makes the downgrade more sensible.

[Kingarabian]

Basically reached 7.0 yesterday and stuck there for a couple of hours.

[xtyphooncyclonex]

Basically reached 7.0 yesterday and stuck there for a couple of hours.

Quite a number of agencies stuck with T7.0, including the JTWC themselves. Yet there was no upgrade.
