Gulf Oil Spill

On April 29, the MODIS image on the Terra satellite captured a wide-view natural-color image of the oil slick (outlined in white) just off the Louisiana coast. The oil slick appears as dull gray interlocking comma shapes, one opaque and the other nearly transparent. Sunglint -- the mirror-like reflection of the sun off the water -- enhances the oil slick’s visibility. The northwestern tip of the oil slick almost touches the Mississippi Delta.

System 90W Losing Its Punch

System 90W on April 29 at 05:11 UTC (1:11 a.m. EDT) and noticed that the storm's center of circulation is now undefined. Forecasters at the Joint Typhoon Warning Center estimate that storm's "center" is located near 10.9 North and 116.3 East, about 355 nautical miles southwest of Manila, Philippines.

The Atmospheric Infrared Sounder known as the AIRS instrument on the Aqua satellite showed deepening convection (rapidly rising air that forms clouds and thunderstorms) as the system moved closer to a mid-latitude trough (elongated area of low pressure). But that deepening or strengthening of convection is expected to be short lived because of the increasing winds battering the system.

The potential for System 90W to develop into a tropical cyclone has now dropped from "Fair" to "Poor" in the next 24 hours.

System 90W (Northwestern Pacific Ocean)

System 90W is already bringing rains to the cities of Narra (a municipality) and Brooke's Point (a first class municipality) in the province of Palawan, Philippines. Even Puerto Princesa City, a first class city and the capital of Palawan, is reporting rainfall from System 90W today.

System 90W's circulation center was near 8.9 North latitude and 120.2 West longitude over the Sulu Sea in the Northwestern Pacific Ocean. Maximum sustained surface winds are estimated at 15 to 20 knots (17-23 mph).

Cyclone 24S Now All Grown Up and Renamed "Tropical Storm Sean"

On Friday, April 23 at 1500 UTC (11 a.m. EDT) Tropical Storm Sean had maximum sustained winds near 45 knots (52 mph). It was about 475 nautical miles north of Learmonth, Australia, near 14.4 South and 113.3 East. It was moving southeast at 4 knots (5 mph).

91S Becomes Tropical Cyclone 24S

Tropical Storm 24S on April 22 at 0708 UTC (3:08 a.m. EDT) showed areas of light to moderate rainfall. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour.

System 91 Looking Good for Tropical Cyclone Development

System 91S has shown increasing organization of its low-level circulation center over the last 12 hours, and favorable conditions for development. The vertical wind shear (winds that can tear a storm apart if strong enough) has decreased, so the potential for 91S to develop into a tropical cyclone is good in the next 24 hours.

At 08:30 UTC (4:30 a.m. EDT) the circulation center of 91S appeared to be near 10.1 degrees South latitude and 116.4 East longitude, and had maximum sustained winds near 30 knots (33 mph). 91S was moving west-southwest near 3 knots (4 mph) and it is currently about 630 nautical miles north-northwest of Port Hedland, Australia.

The ash plume (brown) drifting south and east from Eyjafjallajökull volcano in Iceland

the ash plume from Iceland's Eyjafjallajökull volcano this morning, April 20, as it flew overhead from its vantage point in space.

The ash plume (consisting of fine particles of pulverized rock) at 11:55 UTC (7:55 a.m. EDT). The plume appeared to be lighter in color than the previous few days, and it was drifting south and east over the Northern Atlantic Ocean.

NASA Continues to Track Persistent Iceland Volcano

The continuing eruption of Iceland'sEyjafjallajökull volcano was observed Mon., April 19, 2010, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument onboard NASA's Terra spacecraft. The new image shows a white eruption column being carried toward the south by prevailing winds.

The image is dominated by the gray, ash-laden eruption cloud dispersed south and east by the winds, blowing from the southern Iceland coast toward Europe. The bright red areas mark the hot lava at the current vent (upper left), and the still-hot lava flows from the earlier phases of the eruption (upper center). The high-temperature material is revealed by ASTER's thermal infrared bands.

Disruptive Iceland Volcanic Cloud

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite flew over the volcano at 1:30 p.m. local time (13:29:24 UTC, or 6:29:24 a.m. PDT) on April 15, capturing this false-color infrared image, as well as a visible image of the ash plume.

The images show the ash cloud (in blue) enveloping Iceland and moving eastward over the Shetland Islands and onward to Europe. The ash clouds appear to be at an altitude of 3,658 meters (12,000 feet).

Eyjafjallajokull Volcano over the North Atlantic

The Eyjafjallajokull volcano in Iceland erupted Wednesday, April 14, for the second time this month. The volcano is still spewing ash into the air and the ash clouds are impacting air travel in Northern Europe.

NASA's Terra satellite flew over the volcano the following day at 11:35 UTC (7:35 a.m. EDT) on April 15, 2010, and the Moderate Resolution Imaging Spectroradiometer, or MODIS instrument onboard Terra captured a visible image of the ash plume from Eyjafjallajokull Volcano.

U.S. forecaster sees increased 2010 hurricane threat

The 2010 Atlantic hurricane season will produce an above-average eight hurricanes, four of them major, posing a heightened threat to the U.S. coastline, the Colorado State University hurricane forecasting team predicted on Wednesday.

Tropical Storm Robyn (Southern Indian Ocean)

The Joint Typhoon Warning Center issued their final advisory on Robyn today, April 6 at 09:00 UTC (5 a.m. EDT). At that time, Robyn’s maximum sustained winds were down to 39 mph (35 knots) and weakening. It was located about 365 nautical miles southwest of Cocos Island, near 15.5 South and 91.7 East. It is moving north-northwest near 4 mph (3 knots). Robyn has encountered stronger vertical wind shear and will continue to weaken.

Strong earthquake rocks Mexico

The earthquake that jolted Mexico's Baja California peninsula has killed one man whose home collapsed, a civil protection official says.

Baja California state Civil Protection Director Alfredo Escobedo said the man's home collapsed just outside of Mexicali, close to the epicentre of the 7.2-magnitude quake. Esobedo says there were reports of more people trapped in homes in Mexicali and rescue teams with dogs and digging equipment are rushing to the city from nearby Tijuana.

The quake, which struck at 2240 GMT (8.40am), was at a depth of 32.3 kilometres and was located 26 kilometres south-south-west of Guadalupe Victoria, Baja California, and 64 kilometres south-west of San Luis, in the US state of Arizona, the USGS added.

A number of San Diego residents said the quake was the worst they had felt in decades.

Jess Ponting, an Australian working at San Diego State University, said he was at home when the quake struck. "The main earthquake shook our apartment block and caused a panic up and down the street,"

"I cowered under my kitchen table on the third floor for about 45 seconds as the apartment shook violently and glassware rattled and ornaments and pictures fell off the walls. "After the tremor finished, everyone spilled out on to the streets and started calling loved ones and figuring out what was going on."

Tropical Storm 23S Born in Southern Indian Ocean

Tropical Storm 23S was born today, April 2 about 260 nautical miles west of Cocos Island, Australia, near 11.5 South and 92.5 East. It has maximum sustained winds of 39 mph (35 knots) and is moving southward at around 6 mph (5 knots). Although Cocos Island is not in the direct path of the storm, it was being affected with by thunderstorms in the storm's outer bands.

When the TRMM satellite passed over Tropical Storm 23S on April 2 at 0913 UTC (5:13 a.m. EDT) it measured light to moderate rainfall. Since then, infrared satellite imagery indicated that bands of thunderstorms have consolidated around the center of 23S's center of circulation. Rainfall is likely going to intensify in the system as it strengthens over the weekend. At times rain may be falling in some areas of the storm at up to 2 inches per hour.

Cyclone Paul over the Gulf of Carpentaria, Australia

Warnings Dropped for Ex-Cyclone Paul as NASA Satellites See it Fizzle

NASA's Aqua satellite flew over the remnants of ex-tropical storm Paul early today, April 1 and noticed its circulation and form had weakened in the last 24 hours. All weather warnings for the mainland in the Northern Territory have been cancelled.

On April 1 at 11:15 p.m. CST Darwin time (8:45 a.m. EDT) Paul's remnants were located close to the Northern Territory/Queensland border in the southern Gulf of Carpentaria coast. The low is expected to track inland overnight and continue to weaken over the southern Top End during the next few days.
