NASA Sees Tropical Cyclone Lehar Make Landfall in Eastern India

NASA's Aqua satellite captured an image of Tropical Cyclone Lehar after it weakened to a depression and neared the coast of India on November 29. Lehar made landfall south of Machillipatnam.

At 0300 UTC on Nov. 28/Nov. 27 at 10 p.m. EST, Tropical Depression Lehar was located about 145 nautical miles northeast of Chennai, near 15.0 north and 81.9 east. It was moving to the west-northwest at 10 knots and had maximum sustained winds near 35 knots/40 mph/62 kph. The Joint Typhoon Warning System issued their final warning on the tropical cyclone.

The Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite captured an image of Lehar at 0800 UTC/3 a.m. EST on Nov. 28, about 30 minutes before the cyclone made landfall.

India's Regional Specialized Meteorological Center reported Lehar cross the Andhra Pradesh Coast as a depression and made landfall near latitude 15.9 north and longitude 81.1. east, close to south of Machillipatnam around 0830 UTC/3:30 a.m. EST. The depression moved west-northwest and weakened to a remnant low pressure area. Lehar is expected to dissipate later today.

Nov. 27, 2013 - NASA Watches as India Braces for Tropical Cyclone Lehar [image-108]

Tropical Cyclone Lehar is weakening as it heads for a landfall in eastern India. NASA's Aqua satellite captured an image of the storm nearing the coast today, November 27.

Warnings were in effect in India for northern Andhra Pradesh and southern Odisha as Lehar approaches. Lehar will bring winds, heavy rainfall and storm surge to those Indian states today, and tomorrow. A storm surge of up to 3 meters is possible. 

The MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Lehar nearing the coast of central India on Nov. 27 at 0715 UTC/2:15 a.m. EST. The MODIS image showed bands of thunderstorms extending from the northern and southern quadrants of the storm, wrapping into the center. There was no visible eye, despite Lehar being at minimal hurricane-strength.

At 1500 UTC/10 a.m. EST on November 27, Lehar's maximum sustained winds were near 55 knots/63.2 mph/101.9 kph. Tropical-storm-force winds extended out 105 nautical miles/120.8 miles/194.5 km from the center of circulation, and the center was about 195 nautical miles southeast of Visakhapatnam, India. That puts the center near 15.1 north and 84.2 east. Lehar is generating high and rough seas with wave heights to 24 feet/7.3 meters as it moves to the west-northwest at 12 knots/13.8 mph/22.2 kph.

The Joint Typhoon Warning Center expects Lehar to strengthen a little more before making landfall in eastern India on November 27 at 0700 UTC/2 a.m. EST. By November 28 Lehar is expected to dissipate.

Nov. 26, 2013 - NASA Satellite Tracks Tropical Cyclone Lehar Moving Toward India [image-78][image-94]

Tropical cyclone Lehar, located in the Bay of Bengal, continues to gain intensity while heading toward the same area of India where a much weaker tropical cyclone Helen recently came ashore. NASA's TRMM satellite passed over Lehar and measured rainfall and cloud heights to give scientists an understanding of how the storm is behaving. 

NASA's Tropical Rainfall Measuring Mission satellite called TRMM flew above tropical cyclone Lehar on November 26, 2013 at 0307 UTC/Nov. 25 at 10:07 p.m. EST and captured rainfall data. Rainfall rates occurring in the storm were derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. That data was taken and overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) at NASA's Goddard Space Flight Center in Greenbelt, Md. to create a total picture of rainfall within the tropical cyclone. The TRMM instruments found that rain was falling at a rate greater than 64 mm/~2.5 inches per hour in Lehar's center and in a band of intense rain wrapping around Lehar's northwestern side. Some strong thunderstorms within Lehar were reaching heights above 15.25 km/~9.5 miles.

Warnings are already in effect in India. Northern Andhra Pradesh and southern Odisha are expected to feel Lehar's effects on Wednesday, November 27, when winds are expected to reach up to 91.7 knots/105.6 mph/170 kph.

At 1500 UTC/10 a.m. EST on November 26, Tropical Cyclone Lehar's maximum sustained winds were near 75 knots/86.1 mph/138.9 kph. Tropical-storm-force winds extend up to 100 nautical miles/115.1 miles/185.2 km from the center of the storm or 200 miles/230.2 miles/370.5 km in diameter. Lehar's center was located about 471 nautical miles southeast of Visakhapatnam, India, near 12.9 north and 88.6 east. Lehar was moving to the west-northwest at 9 knots/10.3 mph/16.6 km.

The Joint Typhoon Warning Center or JTWC predicts that Lehar's sustained wind speeds will reach 95 knots/~109 mph on November 27, 2013 and then decrease to about 85 knots/~98 mph before hitting India's east-central coast.

Nov. 25, 2013 - NASA Catches Tropical Cyclone Lehar Over the Andaman Islands [image-51]

The Andaman Islands received an unwelcome visitor on November 25 in the form of Tropical Cyclone Lehar. NASA's Terra satellite captured a picture of the visitor as it was making its exit from the islands and into the Bay of Bengal.

Tropical Depression 05B formed off the west coast of the Malay Peninsula on November 23 and strengthened into Tropical Cyclone Lehar as it moved from the Andaman Sea over the Andaman Islands and is now working its way into the Bay of Bengal and toward India. The Andaman Islands are located in the eastern Bay of Bengal. Burma lies north and east of the island group and India lies to the west.

Tropical Cyclone Lehar was over the Andaman and Nicobar Islands at the time NASA's Terra satellite flew overhead and captured a visible image of the storm. On November 25, 2013 at 04:25 UTC/Nov. 24 11:25 p.m. EST, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard Terra took a picture of the tropical cyclone as the eastern side of the storm covered the island. Most of Cyclone Lehar was west of the island in the Bay of Bengal, although the northeastern edge of the storm extended over west-central Burma, bringing clouds to Yangon, capital city of the Yangon region. By November 26, Lehar was bringing rainfall and gusty winds to the region.

At 1500 UTC/10 a.m. EST on November 25, Tropical Cyclone Lehar had maximum sustained winds near 65 knots/74.8 mph/120.4 kph, achieving hurricane-force. It was centered near 12.6 north and 90.6 east, about 550 nautical miles/633 miles/1,019 km southeast of Visakhapatnam, India. Lehar is moving away from Burma and toward the west-northwest at 7 knots/8 mph/12.9 kph. Lehar is generating 20-foot/6.0 meter high seas

Forecasters at the Joint Typhoon Warning Center expect that warm water temperatures and low wind shear will assist Lehar in intensifying as it moves in a west-northwesterly direction across the Bay of Bengal. Forecasters expect maximum sustained winds to peak near 100 knots/115.1 mph/185.2 kph before making landfall in eastern India.

As a result warnings are already in effect for India. Lehar's winds area expected to affect Northern Andhra Pradesh and southern Odisha by Wednesday, November 27.
