NASA watching 2 areas in the Caribbean, 1 is a rainmaker

06.06.2011
Keeping an eye out for tropical cyclone development

There are two low pressure areas in the Caribbean Sea for future development into tropical cyclones, although the chances are near zero for one, and minimal for the other. The GOES-13 satellite has been following the life of System 93L, which is one of those systems. The second low pressure area may not develop over the weekend, but threatens heavy rain in Hispaniola, Cuba and Jamaica.

The GOES-13 satellite provides images of the U.S. east coast, Atlantic and Caribbean Sea continually every day. In an image from 1731 UTC (1:31 p.m. EDT) today, June 3, the low pressure area known as System 93L is located in the far western Caribbean Sea. It appears as a small area of cloudiness, about 275 miles east-southeast of Brownsville, Texas. GOES-13 has been tracking that low pressure area for over a week, since it developed off the North Carolina coast and tracked across Florida last weekend and into the Gulf of Mexico.

Wind shear will continue to prevent System 93L from developing further over the weekend, so there's a "near zero percent chance" it will develop in the next 48 hours, according to the National Hurricane Center. System 93L now appears to be moving northwestward between 10 and 15 mph after tracking southward earlier this week.

A second low pressure area is also catching the eye of forecasters who use GOES-13 satellite data. The second low is located a couple hundred miles south of Jamaica and has become a little better defined today. That low pressure area appears to dwarf System 93L in size, as the center of circulation is surrounded by a large area of cloudiness.

One factor that keeps that low's chance for development down to 20% this weekend is the movement of dry air into its western side. Dry air prevents formation of the thunderstorms that power a tropical cyclone.

Despite the low chances for development, however, this low is expected to bring heavy rainfall, flash flooding and mudslides over portions of Jamaica, Haiti, the Dominican Republic and southeastern Cuba over the next couple of days. That low is forecast to remain almost stationary over the west-central Caribbean Sea for the next couple of days.

The image of both low pressure areas was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. The series of Geostationary Operational Environmental Satellites (GOES) are managed by NOAA, and the NASA/NOAA GOES Project creates images and animations from those satellites.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
