NASA Satellite Sees Developing Tropical Depression Near Philippines

System 91W appears ripe to become Tropical Depression 4 in the next couple of days as it continues moving north and parallels the east coast of the Philippines. NASA's Aqua satellite captured a visible image of the developing low pressure area as it passed overhead in space on June 17. On June 16 at 2200 UTC (6 p.m. EDT) System 91W was located near 13.5N and 126.9E, about 355 miles east-southeast of Manila, Philippines. NASA's Aqua satellite passed over System 91W on June 17 at 05:08 UTC (1:08 a.m. EDT) and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard captured a visible image of the consolidating storm. Satellite imagery showed strong bands of thunderstorms over the northern and southern quadrants of the storm. The low-level center of circulation appears to be consolidating, and the banding of thunderstorms around it have improved in the last day. According to the Joint Typhoon Warning Center, System 91W has a high chance of becoming Tropical Depression 4 in the next day or two. Computer models indicate that it will continue tracking northward and parallel the coast of the Philippines over the next couple of days and residents along the coast can expect rough seas, gusty winds and rain as the low pressure area moves north.

Tropical Depression 02 (Atlantic)

Tropical Depression 2 formed in the western Caribbean Sea during the early afternoon hours (Eastern Daylight Time) on June 17. NOAA’s GOES-13 satellite captured an image of the storm as it consolidated enough to become a tropical depression while approaching the coast of Belize. NOAA’s GOES-13 satellite sits in a fixed orbit and monitors the weather in the eastern half of the continental United States and the Atlantic Ocean. NASA’s GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Maryland uses the data from GOES-13 and creates imagery. NASA’s GOES Project created an image of Tropical Depression 2 from June 17 at 1:10 p.m. EDT. Looking closely at the imagery, strong thunderstorms are firing up around the center of circulation, just off-shore from Belize. The clouds associated with the depression stretch much farther, from far western Cuba, to the eastern Yucatan Peninsula, and over Belize and Honduras.

Satellites See Tropical Storm Barry Form in the Bay of Campeche

The National Hurricane Center designated the low pressure area as Tropical Depression 2 at 11 a.m. EDT. At that time it had maximum sustained winds near 35 mph (55 kph) and was moving to the west-northwest at 13 mph (20 kph). Tropical Depression 2 is located near 16.2 north and 87.6 west, about 60 miles (95 km) east of Monkey River Town, Belize.The center of the depression will move inland over southern Belize this afternoon where no change in strength is expected as it moves over land. The depression could emerge into the Bay of Campeche on Tuesday, according to the National Hurricane Center (NHC). NHC noted that an increase in strength is possible on Tuesday if the center emerges into the Bay of Campeche. If that happens, Tropical Depression 2 could become Tropical Storm Barry.The second tropical storm of the Atlantic hurricane season formed close to where the second storm of the Eastern Pacific season died, in the Bay of Campeche.Tropical Storm Barbara fell apart after crossing Mexico and moving into the Bay of Campeche two weeks ago, and now the second named storm of the Atlantic season formed there. Tropical Storm Barry strengthened from tropical depression 2 as of 1:45 p.m. EDT on June 19.At that time, Barry's center was located near 19.6 north latitude and 95.1 west longitude, just 75 miles (115 km) east- northeast of Veracruz, Mexico, where it is expected to make landfall in the next day. Maximum sustained winds are now up to 40 mph (65 kph), and Barry is moving west at 10 mph. Minimum central pressure is near 1005 millibars. Tropical Storm Warnings are in effect along the coast near Veracruz.NOAA's GOES-13 satellite captured a visible image of Tropical Storm Barry just after it became a tropical storm on June 19. The GOES-13 image showed that Barry had attained better circulation in the last 24 hours. The image was created by NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.

Rare Clear View of Alaska

On most days, relentless rivers of clouds wash over Alaska, obscuring most of the state's 6,640 miles (10,690 kilometers) of coastline and 586,000 square miles (1,518,000 square kilometers) of land. The south coast of Alaska even has the dubious distinction of being the cloudiest region of the United States, with some locations averaging more than 340 cloudy days per year. That was certainly not the case on June 17, 2013, the date that the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite acquired this rare, nearly cloud-free view of the state. The absence of clouds exposed a striking tapestry of water, ice, land, forests, and even wildfires. Snow-covered mountains such as the Alaska Range and Chugach Mountains were visible in southern Alaska, while the arc of mountains that make up the Brooks Range dominated the northern part of the state. The Yukon River -- the longest in Alaska and the third longest in the United States -- wound its way through the green boreal forests that inhabit the interior of the state. Plumes of sediment and glacial dust poured into the Gulf of Alaska from the Copper River. And Iliamna Lake, the largest in Alaska, was ice free. The same ridge of high pressure that cleared Alaska's skies also brought stifling temperatures to many areas accustomed to chilly June days. Talkeetna, a town about 100 miles north of Anchorage, saw temperatures reach 96°F (36°C) on June 17. Other towns in southern Alaska set all-time record highs, including Cordova, Valez, and Seward. The high temperatures also helped fuel wildfires and hastened the breakup of sea ice in the Chukchi Sea.Image Credit: NASA/Jeff Schmaltz, LANCE MODIS Rapid Response Team, NASA GSFCCaption: Adam Voiland
