System 91L is a tropical low pressure area that has been lingering in the northwestern Caribbean Sea and the Gulf of Mexico for several days. The low pressure area is located in the central Gulf of Mexico and covers a large area. It has a large area of disorganized thunderstorms and strong gusty winds over the southeastern Gulf.
These two infrared images of System 91L taken from the AIRS instrument aboard NASA's Aqua satellite show the areas with the coldest cloud top temperatures and strongest thunderstorms (purple) on June 4 at 18:47 UTC and June 5 at 06:59 UTC. The coldest temperatures were -63F/-52C and also indicated areas of likely heavy rainfall.

The National Hurricane Center (NHC) noted that thunderstorm activity increased on June 5, compared to June 4, but the center of circulation is poorly-defined.
NASA's Aqua satellite passed over System 91L on June 4 and June 5 and captured infrared images of the storm. The two infrared images of System 91L showed areas with the coldest cloud top temperatures and strongest thunderstorms moved to the north. Images were captured on June 4 at 18:47 UTC (2:47 p.m. EDT) and June 5 at 06:59 UTC (2:59 a.m. EDT). The coldest temperatures were near -63F/-52C and indicated areas of likely heavy rainfall. In the June 4 image, the strongest thunderstorms were between Mexico's Yucatan Peninsula and western Cuba. On June 5, those strongest thunderstorms were over western Cuba and stretched north, over southwestern Florida.
NOAA's GOES-14 satellite captured a visible image of System 91L the on June 6 at 17:10 UTC (1:10 p.m. EDT). The image showed that System 91L's cloud cover extended from Mexico's Yucatan Peninsula east to Cuba and north over the state of Florida.
Southern Florida, the Florida Keys and western Cuba can expect heavy rain, inland flooding and gusty winds over the next couple of days. Isolated tornadoes are also possible over the Florida peninsula late tonight, June 6, through Thursday.
Currently on June 6, many areas of Florida are under watches and advisories. For example, in Tampa, the following are in effect from June 5 through June 8 at 8 p.m. EDT: a Coastal Flood Advisory; a High Surf Advisory; a Rip Current Statement; and a Flood Watch. Current rain totals expected by the National Weather Service are between 3 and 5 inches of rain today, June 6.
The NHC gives System 91L a high chance (60%) of becoming a subtropical or tropical cyclone within the next 2 days. At the NHC 2 p.m. EDT update on June 6, forecasters noted there is potential for this system to become a Tropical depression or storm before it moves across northern Florida late Thursday or Thursday night.
Even if System 91L does not become a tropical storm, the National Weather Service expects the low to soak the southeastern U.S. and Mid-Atlantic states over the next couple of days as it moves northward.

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
Temperature measurements possible even on the smallest scale / Molecular ruby for use in material sciences, biology, and medicine
Chemists at Johannes Gutenberg University Mainz (JGU) in cooperation with researchers of the German Federal Institute for Materials Research and Testing (BAM)...
Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
