10/26/10 Burma (Washington Post) – A dangerous tropical cyclone over the northern Indian ocean, Giri, rapidly strengthened overnight before making landfall in Burma, also known as Myanmar, today (Friday). The storm comes two and a half years after Tropical Cyclone Nargis devastated that country, claiming more than 100,000 lives.
The Navy’s Joint Typhoon Warning Center wrote this morning (Friday) that Giri’s maximum sustained winds intensified by over 58 mph (50 knots) in 12 hours “indicative of explosive intensification.”
As of 7 a.m. this morning – just hours prior to landfall – maximum sustained winds were 140 to 155 mph (125-135 knots) with gusts to 190 mph (165 knots) – equivalent to a high end Category 4 hurricane. The storm was merely at category 1 strength yesterday.
Nargis, probably the worst natural disaster in Burma’s history, had weaker sustained winds of 130-135 mph at landfall. However, most of the casualties from Nargis arose from the storm surge which pushed a 13 foot wall of water across the Irrawaddy Delta region, drowning thousands.
As Giri is making landfall further north than Nargis, away from the vulnerable, low lying Irrawaddy Delta, the toll may not be as high.
AccuWeather reported: “The site of landfall was about 40 miles southeast of Sittwe (Akyab), or 250 miles northwest of Yangon, the Myanmar [Burma] capital. It includes many coastal islands, some of them low-lying with many tidal channels, but also some high ground.”
Peter Webster, an atmospheric scientist at Georgia Tech and an expert on weather impacts in the region of the Bay of Bengal (India, Bangladesh, and Burma), told the Capital Weather Gang:
[The area impacted by] Giri has much more elevation than the Irrawaddy basin that extends inland for 10s of km at sea level. So the consequences of Giri will be different to those of Nargis. Instead of storm surges the main impacts will be from wind damage and rainfall flooding.
