TYPHOON 06W (NIDA), LOCATED APPROXIMATELY 379 NM EAST-SOUTHEAST

IS EVIDENT THAT TY 06W HAS MOVED SUFFICIENTLY OFF THE COAST OF LUZON
MAINTAINING VERY GOOD STRUCTURE. THE INITIAL INTENSITY IS ASSESSED
AT 65 KNOTS AND IS BASED ON OBJECTIVE DVORAK CURRENT INTENSITY
ESTIMATES OF T4.0 (65 KNOTS) FROM PGTW AND RJTD. ENVIRONMENTAL
CONDITIONS ARE STILL VERY FAVORABLE WITH SEA SURFACE TEMPERATURES IN
EXCESS OF 30 CELSIUS, STRONG DIFFLUENCE ALOFT, AND VERTICAL WIND

This system is so BROAD.

Question is in which side of the Pearl River Delta will it strike. Most forecast tells that it will hit the east side but IF it goes west, this could be a massive storm surge generator. HKO mentioned that Nida's arrival might coincide with a high tide event

:uarrow: Agree. A slight difference in the track would make a huge difference in the weather conditions over Hong Kong. Aside from the potential storm surge, winds would be stronger if this makes landfall to the west of Hong Kong because they are not blocked by the mountains.

Luzon did a number on the core. It's trying to reorganize now, but the size of it is going to prevent it from doing any strengthening in a hurry.

That microwave really is a thing of beauty, eh?

I had been wondering why this hasn't been getting that much attention...

Storms like Nida are comparable to Hurricane Ike, Typhoon Fitow, Typhoon Morakot, or Tropical Storm Bilis. Someone is going to get a massive flooding issue, and of course, there is the whole weaker top strength but more prevalent strong winds that were a feature of Ike or Fitow. It is rare for the material parts of the Pearl River Delta to get a real typhoon landfall. 2003 Dujuan crossed it, and Vicente 2012 and Usagi 2013 hit on either side. Heck, Mujigae might have been the scariest, what with the tornados. Also, I think it looks unlikely that the area would be would missed, a la 2006 Chanchu or 2010 Megi.

And a note on the flooding thing--there is some hint of a possibility that the typhoon will drag in SCS moisture after itself and help add rainfall.

Interesting that a major city of over 7 million in the vulnerable Pearl River Delta, more than any U.S city in the Gulf coast and Florida getting threatened by a typhoon strength system is getting little attention...I guess that invest 97L has them occupied...

No. 8 Northwest Gale or Storm Signal

Tropical Cyclone Bulletin

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

The No. 8 Northwest Gale or Storm Signal is in force.

This means that winds with mean speeds of 63 kilometres per hour or more are expected from the northwest quarter.

At 11 p.m., Typhoon Nida was centred about 170 kilometres east-southeast of Hong Kong (near 22.0 degrees north 115.8 degrees east) and is forecast to move west-northwest at about 25 kilometres per hour towards the vicinity of the Pearl River Estuary.

As Nida edges further closer, local winds will strengthen rapidly. In the past hour, the maximum sustained winds recorded at Tate's Cairn and Waglan Island were 78 and 64 kilometres per hour with maximum gusts 107 and 81 kilometres per hour respectively. Squalls, heavy rain and rough seas will progressively affect Hong Kong. Storm surge brought by Nida may cause flooding or sea water intrusion in some low-lying areas tomorrow morning.

According to the present forecast track, Nida will be closet to Hong Kong tomorrow morning. It will skirt within 50 km of the territory. The Number 8 Gale or Storm Signal is expected to persist tonight and most of the time tomorrow morning.

(Precautionary Announcements with No. 8 Signal)

1. Complete all precautions in your home. Lock all windows and doors, fit bars into position and insert reinforced shutters and gates if they are available. Adhesive tape fixed to large window-panes in exposed positions will reduce damage by broken glass. Storm water drains should be cleared of leaves and rubbish.

2. Do not stand near windows on the exposed side of your home. Move all furniture and valuables away from these areas. Make sure you have a safe place to shelter, should windows be broken.

3. Since seas are rough and there are swells, you are advised to stay away from the shoreline and not to engage in water sports.

4. Owners of neon signs are reminded that they should now arrange for the electricity supply to their signs to be cut off.

5. Please listen to radio or watch TV for the latest weather information broadcast. You can also browse the Hong Kong Observatory's web site for the information.

Dispatched by Hong Kong Observatory at 22:45 HKT on 01.08.2016

Nida seems to be making landfall near the Dapeng Peninsula. Lowest pressure recorded was only around 979 mb. Winds over Hong Kong are not as strong as expected as well.

REMARKS:
020300Z POSITION NEAR 23.0N 112.9E.
TYPHOON (TY) 06W (NIDA), LOCATED APPROXIMATELY 49 NM NORTHWEST OF
HONG KONG, HAS TRACKED WEST-NORTHWESTWARD AT 15 KNOTS OVER THE PAST
SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
TIGHTLY WRAPPED LOW LEVEL CIRCULATION CENTER THAT IS NOW POSITIONED
OVER LAND. THIS IS CONFIRMED BY THE HONG KONG RADAR LOOP WHICH
PROVIDES HIGH CONFIDENCE IN THE CURRENT POSITION. CONVECTION IS
RAPIDLY DETERIORATING DUE TO LAND INTERACTION, SPECIFICALLY ALONG
THE WESTERN PERIPHERY. THE SYSTEM WILL CONTINUE TO MOVE
NORTHWESTWARD, FURTHER INLAND, AND FULLY DISSIPATE BY THE END OF THE
FORECAST PERIOD. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE
JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY
MONITORED FOR SIGNS OF REGENERATION

Regeneration? IT'S A TYPHOON!
