It's a good thing Hato is quickly running out of water.

Tropical Cyclone Warning Bulletin

Here is the latest Tropical Cyclone Warning Bulletin issued by the Hong Kong Observatory.

The Hurricane Signal, No. 10, was issued at 9:10 a.m.

This means that winds with mean speeds of 118 kilometres per hour or more are expected.

At 9 a.m., Severe Typhoon Hato was centred about 80 kilometres south of Hong Kong Observatory (near 21.6 degrees north 114.3 degrees east) and is forecast to move west-northwest at about 25 kilometres per hour towards the vicinity of the Pearl River Estuary.

Hurricane force winds are affecting the southeastern part of Hong Kong. With Hato moving towards the western part of the Pearl River Estuary, local winds will turn gradually to the southeast, and hurricane force winds will affect other parts of the territory. Hurricane Signal No. 10 is expected to remain in force for a few hours. You are advised to remain where you are if protected and be prepared for destructive winds, possible flooding and landslip.

A high water level of 3 metres above chart datum has already been recorded at Quarry Bay and is expected to further increase. A high water level of about 5.0 metres above chart datum is expected at Tolo Harbour around noon time. Severe sea water flooding may occur in low-lying areas. Members of the public should stay away from the shoreline and low-lying areas.

In the past hour, the maximum sustained winds recorded at Tate's Cairn and Waglan Island were 128 and 127 kilometres per hour with maximum gusts 168 and 150 kilometres per hour respectively.

Ring of lightning now appearing around of the eye of Hato, indicating further intensification as it passes south of Hong Kong. Very impressive lightning display.

SUBJ/PROGNOSTIC REASONING FOR TYPHOON 15W (HATO) WARNING NR
13//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS. TYPHOON 15W (HATO), LOCATED
APPROXIMATELY 53 NM SOUTH-SOUTHEAST OF HONG KONG, HAS TRACKED WEST-
NORTHWESTWARD AT 15 KNOTS OVER THE
PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
BROAD AREA OF DENSE OVERCAST WITH AN EYE FEATURE FORMING BRIEFLY
THEN BECOMING CLOUD-FILLED OVER THE LAST SIX HOURS. A 222304Z 91GHZ
SSMIS IMAGE SHOWS AN IMPRESSIVE CORE OF DEEP CONVECTION IN A NEAR
SYMMETRIC RING AROUND THE SYSTEM CENTER. THERE IS HIGH CONFIDENCE IN
THE INITIAL POSITION BASED ON THE MICROWAVE IMAGE. THE INITIAL
INTENSITY WAS RAISED HIGHER THAN EXPECTED TO 90 KNOTS BASED ON THE
CONSOLIDATING CONVECTIVE STRUCTURE WITH DVORAK ESTIMATES RANGING
FROM T4.5 TO T5.0 (77 TO 90 KNOTS). UPPER-LEVEL ANALYSIS SHOWS
SIGNIFICANT IMPROVEMENT IN VERTICAL POLEWARD OUTFLOW, WHILE
EQUATORWARD OUTFLOW AND ASSOCIATED DIFFLUENCE HAVE BEEN PERSISTENTLY
FAVORABLE. THERE IS A WEAK TROUGH NORTHEAST OF TY 15W PREVIOUSLY
HINDERING CONVECTIVE ACTIVITY ON THE RESPECTIVE FLANK BUT IS NOW
SUFFICIENTLY EAST OF THE SYSTEM. SSTS IN THE REGION ARE ALSO VERY
SUPPORTIVE NEAR 31 CELSIUS. CURRENTLY TY 15W IS TRACKING WEST-
NORTHWEST ALONG A DEEP-LAYERED SUBTROPICAL RIDGE TO THE NORTH.
A. NO SIGNIFICANT CHANGE TO THE FORECAST PHILOSOPHY FROM THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TY 15W IS FORECAST TO CONTINUE TRACKING WEST-NORTHWESTWARD
UNDER THE STEERING INFLUENCE OF THE DEEP-LAYERED STR ENTRENCHED TO
THE NORTH. ENVIRONMENTAL CONDITIONS ARE EXPECTED TO REMAIN MOSTLY
FAVORABLE OVER THE NEXT 6 HOURS SUSTAINING THE CURRENT INTENSITY
BEFORE MAKING LANDFALL JUST SOUTHWEST OF HONG KONG IN THE NEXT 6 TO
12 HOURS. THE SYSTEM WILL CONTINUE TO TRACK INLAND INTERACTING WITH
THE MOUNTAINOUS TERRAIN AND RAPIDLY DISSIPATING TY 15W BY TAU 36.
DYNAMIC MODEL GUIDANCE SHOWS VERY TIGHT GROUPING. THE FORECAST TRACK
IS PLACED NEAR THE MULTI-MODEL CONSENSUS WITH HIGH CONFIDENCE.//

Made landfall at 90 knots however it was rapidly intensifying and Dvorak from JTWC and KNES came in at 5.5 and ADT peaked at 105 knots. Likely made landfall as a Cat 3.

According to the latest JTWC report, Hato reached minimal Category 3 status @ 03z, shortly before landfall...
