Eastern Pacific Season Off with a Bang: Amanda is First Major Hurricane

28.05.2014

The first tropical cyclone of the Eastern Pacific hurricane season grew into a major hurricane as Hurricane Amanda reached Category 4 status on the Saffir-Simpson scale over the Memorial Day holiday weekend. NASA and NOAA satellites watched as Amanda developed an eye while strengthening.

Fortunately, Amanda is far enough away from coastal Mexico that no watches or warnings are in effect today, May 27. 


On May 25 at 2100 UTC/5 p.m. EDT the MODIS instrument aboard NASA's Aqua satellite captured this visible image that revealed an eye in Hurricane Amanda.

On Sunday, May 25, Amanda strengthened into the first Major Hurricane in the Eastern Pacific Ocean. Maximum sustained winds were near 155 mph (250 kph). Amanda was centered near 11.8 north and 111.1 west, about 770 miles (1,240 km) south of the southern tip of Baja California.

Amanda is a Category 4 on the Saffir-Simpson scale. Minimum central pressure was near 932 millibars, and Amanda was crawling to the north at 2 mph (4 kph). Visible imagery from MODIS (Moderate Resolution Imaging Spectroradiometer) instrument aboard NASA's Aqua satellite and NOAA's GOES-West satellite captured imagery that revealed an eye in Hurricane Amanda.

On Monday, May 26, Hurricane Amanda started to weaken from its peak at a Category 4 status on the Saffir-Simpson scale. An image from NOAA's GOES-West satellite at 1200 UTC/5:00 a.m. PDT showed that Amanda's eye had become cloud-filled.

Amanda's maximum sustained winds were near 140 mph (220 kph) and the hurricane was moving to the north-northwest at 7 mph/ (11 kph). Amanda was centered near 13.1 north and 111.6 west, about 685 miles (1,105 km) south of the southern tip of Baja California.

On Tuesday, May 26 at 1500 UTC (11 a.m. EDT/8 a.m. PDT), Amanda's maximum sustained winds were near 120 mph (195 kph). Amanda is a category three hurricane on the Saffir-Simpson Hurricane wind scale. 

Amanda was centered near 14.7 north latitude and 112.3 west longitude, about 585 miles (945 km) south-southwest of the southern tip of Baja California, Mexico. Amanda was moving to the north-northwest at 6 mph (9 kph) and had a minimum central pressure of 957 millibars.

The U.S. Naval Research Laboratory in Washington, D.C. created a composite image using rainfall rate data from NASA-JAXA's Tropical Rainfall Measuring Mission (TRMM) satellite and infrared imagery from NOAA's GOES-West satellite to create a comprehensive look at Amanda. The infrared data showed the cloud extent, and the TRMM data showed heavy rainfall around Amanda's center falling at 1.4 inches (35 mm) per hour.

The National Hurricane Center forecasts weakening during the next 48 hours. In fact, NHC forecasters expect Amanda to weaken to a tropical storm by Thursday.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
