Taiwan Typhoons

Typhoon NEPARTAK. 

The edge of the storm will reach Taiwan at 2pm Thursday July 7th.  The center of the storm will make Landfall at 3am Friday July 8th at Taidong.  The storm will be past Taiwan Saturday July 9th at 5am.

The storm is expected to bring heavy rain to all parts of Taiwan from 11:45pm Thursday July 7th through all of Friday July 8th and into Saturday.  Highest rains will be in the mountain areas of Kaohsiung, Pingtung & Hualien - upwards of 900mm.  If your car or scooter in a basement or underground you want to get it to street level.

This is a powerful storm.  Basically - stay inside while it is here.  Winds causing flying debris can be as dangerous as flooding.

Typhoon Q & A

What things should one do to prepare for a typhoon?

  1. In the aftermath of many storms, the hardest hit areas can have their water mains shut down. This can last for several days. Having a 5 gallon bottle of water, or two, in a closet somewhere can make drinking, eating (and showering or using the toilet) a lot easier. It won't be any fun getting them, but if you are in an area apt to be hard hit, having them there will make you pretty happy if things go bad in terms of water in your neighborhood.
  2. Sea warnings are announced 24 in advance radius affecting shipping lanes. Land Warnings 18 hours in advance of the radius of the storm reaching land.
  3. After wind damage, the most common problem faced in Taiwan comes from flooding. If you are in an area that is likely to be hard hit and on a ground floor or in a basement structure, get yourself and your stuff to a second floor.

What does "maximum sustained wind" mean ?

The maximum sustained wind mentioned are the highest 1 min surface winds occurring within the circulation of the system. These "surface" winds are those observed (or, more often, estimated) to occur at the standard meteorological height of 10 m (33 ft) in an unobstructed exposure (i.e., not blocked by buildings or trees).

During a Typhoon/hurricane are you supposed to have the windows and doors on the storm side closed and the windows and doors on the lee side open?

NO! All of the doors and windows should be closed throughout the duration of the hurricane. The pressure differences between the inside of your house and the outside in the storm do not build up enough to cause your windows to blow out.


  1. Tropical Disturbance (Tropical Wave): Unorganized mass of thunderstorms, very little, if any, organized wind circulation.
  2. Tropical Depression: Has evidence of closed wind circulation around a center with sustained winds from 20-34 knots (23-39 mph), and the storm generally doesn't feel very good about itself.
  3. Tropical Storm: Maximum sustained winds are from 35-64 knots (40-74 mph). The storm is named once it reaches tropical storm strength.
    The Taiwan weather service categorizes Tropical Storms as Category 1 Typhoons. (In Taiwan there are only 3 storm levels.)
  4. Typhoon or Hurricane: Maximum sustained winds exceed 64 knots (74 mph). Fives categories below:
