Tropical Cyclone Chapala: Historic Storm

Update: Saturday Morning

The storm is likely to start affecting land Sunday, and to make landfall late Sunday or some time Monday, probably as a Category I equivalent.

Meanwhile this is the first tropical storm I’ve ever seen associated on the Internet with sites that seem to want to plant viruses on your computer. Stick with trusted sources, like the Wonder Blog or Yours Truly.

Update Friday AM:

TC Chapala is expected to be the strongest cyclone ever recorded in this part of the Indian Ocean basin. At present the storm is strengthening and is just under Category 5 strength (it will probably remain in the Category 4 range). This is the third time a major tropical cyclone has formed in this area since 1945, and the last two were Gonu in 2007 and Phet in 2010. Chapala may become the first tropical cyclone in recorded history to directly hit Yemen.

The storm is expected to bring significant rain to parts of Yemen and Oman, and a bit of Saudi Arabia. Coastal areas of Yemen may have up to a foot of rain. Some parts of this arid region will experience about eight years worth of rainfall over a 48 hour period, according to the Weather Channel.

The storm surge could be as much as three meters (15 feet). While the storm is expected to weaken before landfall, it is likely to retain major cyclone/hurricane status.

The reason the storm formed and became so strong is likely the record breaking sea surface temperatures in the region. These sea surface temperatures partly the result of El Nino, but also, of overall global warming.

I don’t think there are a lot of tropical cyclones (hurricanes) in the Indian Basin, but one is forming up and is expected to be pretty severe when it hits the southern portion of the Arabian Peninsula.

From the Current Storm Information section on Wikipedia:

As of 17:30 IST (12:00 UTC), 29 October 2015, Severe Cyclonic Storm Chapala was located near latitude 14.1°N and longitude 63.3°E, about 1,040 km (650 mi) east-southeast of Salalah, Oman and 1,150 km (710 mi) west-southwest of Mumbai, India. Maximum sustained 3-minute winds are estimated near 100 km/h (60 mph), gusting to 120 km/h (75 mph). Minimum central pressure is about 992 hPa (29.29 inHg). Dvorak intensity is at T3.5. The storm is expected to move west-northwestwards, intensify into a very severe cyclonic storm in the next 12 hours and subsequently develop into an extremely severe cyclonic storm in the next 48 hours. It is then expected to move towards the eastern part of Yemen or the southern part of Oman.
