Kalmaegi will be slightly weaker than expected.

Satellite image of Typhoon Kalmaegi, which is brewing east of Philippines. Time 0300 HRS GMT September 12, 2014.

JTWC has confirmed what we had predicted yesterday. It says it is going to hit Guangdong province of China after moving over north Philippines on September 17, 2014 noon local time.

It also says the typhoon is going to be weaker than expected. When it hits the Chinese coast winds will be around 150 kph.Even that is nothing to sneeze at. It can wreak havoc. Also there is still time. And storms are by nature very unpredictable. Who knows. The Hainan authorities will have to be fully prepared.

Also Typhoon Kalmaegi is going to hit southern Guangdong province in the solar plexus. Hainan island is not the epicenter. Leizhou and Wushi will bear the brunt.

Moreover the typhoon is going pass the strip of Chinese territory and move into Gulf of Tonking and hit Vietnam at Haiphong on September 17, 2014 evening.

The expected typhoon may turn out to be weaker (By US standards it will be a Category 2 storm) but it is going to bring very heavy rains to all the countries it will pass through. A glance at the rainfall prediction maps says it all.

Category	Wind speeds
Five	≥70 m/s, ≥137 knots ≥157 mph, ≥252 km/h
Four	58–70 m/s, 113–136 knots 130–156 mph, 209–251 km/h
Three	50–58 m/s, 96–112 knots 111–129 mph, 178–208 km/h
Two	43–49 m/s, 83–95 knots 96–110 mph, 154–177 km/h
One	33–42 m/s, 64–82 knots 74–95 mph, 119–153 km/h

Massive Typhoon KALMAEGI (LUIS) To Hit North Philippines On September 15, 2014

The birth of a storm: Image of tropical depression W15 taken a few hours ago (See the arrow). Typhoon Kalmaegi has been born.

Typhoon KALMAEGI will be at its strongest on September 16, 2014, as it hurtles towards southern China and Vietnam.

A tropical depression has formed east of Philippines. It has been named 15W. An innocuous title. But when one thinks what it is going to turn into one shudders a little.

The system is going to intensify into a raging typhoon. And it is going to hit northern Philippines on September 15th with winds of 185 kph which may peak at a massive 232 kph!

I suppose the Philippines authorities must have already swung into action. The country is no stranger to cyclones but this system is going to be big bad and very mean.

The worst affected areas will be in northern part of the country. Ilocos, Cordillera, and Cagayan Valley will be worst affected. Capital Manila (Quezon City) will escape from the strongest winds but will receive heavy rains.

What is not widely known is that this cyclone Kalmaegi is not going to dissipate after hitting Philippines. It will lose some steam as it cross northern Philippines but will gain strength in the South China Sea. It will then turn into what we call a "monster" storm and move westward. It will hit southern Guangdong province of China with great ferocity on September 17, 2014, noon (local time). The affected areas will be Leizhou, Wushi and perhaps Zhanjiang.

Twelve hours later. September 17, 2014 night Kalmaegi will impact north Vietnam. Haiphong will face the brunt of the fury of the storm. Massive wind speeds and torrential rains will what Haiphong and Hanoi will witness on that night.

XWF Weather Forecast Map: September 14, 2014. Sunday night. Typhoon Kalmaegi about to enter northern Philippines. Note that wind speeds in the maps are in knots. 1 knot is about 1.852 kph. So imagine!

September 17, 2014. Wednesday noon (local time). Kalmaegi about to hit the southern tip of Guangdong province.

The night of September 17, 2014. Wednesday. Kalmaegi hits northern Vietnam. Haiphong will be worst hit.

This is how Kalmaegi will go says JTWC (Joint Typhoon Warning Center)
