30,000 lightning strikes, orange warnings and severe events: don’t call it ‘squall line’, call it ‘new normal’

by

During the early morning and early hours of this Wednesday, November 5, the arrival of a cold front to the Peninsula has caused a very active squall line throughout the southwest. And, in this case, saying “very active” is not an exaggeration: the images that they come to us from Portugal they are incredible and at the moment, he is heading to Extremadura and Western Andalusia. The interesting thing is that we no longer talk about meteorological information, we begin to enter the field of Okay, but what is a squall line? This is an organized storm system that, often ahead of a cold front, forms in a line. Due to its structure, this phenomenon causes strong and destructive winds, torrential rains, hail and lightning. In addition, they are characterized by advancing very quickly and being able to cause significant damage. In Xataka The "tropicalization" of the atmosphere is going to change Spain and not exactly for the better And so it has been. Portugal’s Civil Protection recorded more than 150 nighttime incidents and, as the Portuguese press explainedit is not just the problems caused by the rain and wind; is that tens of thousands of electric shocks have been recorded. About 30,000 in a few hours. Given this, AEMET activated orange noticesin Galicia, Extremadura and Andalusia. In addition, 122 Extremadura is prepared for rains of 5–20 l/m² in very short periods of time. It’s not a lot of water, but in these circumstances it can cause a lot of problems. Aren’t we talking about autumn showers? No, we are not talking about loose showers: it is an organized convection capable of producing severe gusts, hail and wet blowouts. They are formations that trigger the risk on urban areas, electrical networks and mobility. It’s another episode of “This is not just an Atlantic storm” that has been with us for weeks now. It is true that November is a typical month for hallways in the southwest; but the data suggests that we are facing something more. {“videoId”:”x89b35l”,”autoplay”:false,”title”:”PROFESSIONAL STORM CHASERS_ this is their daily life”, “tag”:””, “duration”:”400″} What is really happening? In technical terms, we are talking about the arrival of an Atlantic trough and cold front with sufficient shear to organize convection and force a quasi-linear system. Ambient humidity does the rest and that is the key. As we said a few days agothat area of ​​the peninsula is prone to low convergences that, with adequate shear and sufficient humidity,They organize convectively very easily. As connections with the Gulf of Mexico (the famous ‘rivers of moisture’) become more common and, with them, the available humidity grows: these systems will become more frequent and more intense. It is the same as occurs in the Mediterranean with DANAs: It doesn’t matter if climate change causes more or not, the amount of “available fuel” makes any spark turn into a fire. Meteorologically speaking, of course.

In case we had not had enough problems in the electricity network, a “severe” solar storm has come to complicate it

by

The closeness of the Pico de Activity of the last solar cycle implies stirred times in the field of “spatial meteorology.” And we have seen one of the most important during these days, a “severe” geomagnetic storm caused by this activity. Geomagnetic storm. The last two days have been days of “intense” solar activity. The geomagnetic storm has reached a Kp = 8 index, which implies that it has been a “severe” storm, from G4 category (On a scale that goes to G5). The value of the index has descended since then: the last data offered by the NOAA spatial meteorological prediction (National Oceanic and Atmospheric Administration) indicates that the value Average Index KP In the last three hours it has been kp = 6. Despite this, spatial time is still scrambled and According to forecasts He will continue to be until tomorrow. An ejection of coronal mass. According to He explained yesterday The Spanish Space Agency through a statement, the origin of this activity is in a high -speed coronal mass ejection (CME), associated solar fulguration of class M8.2 and with origin in the Ar4100 active region. KP 8. What does that mean of kp = 8? The K Geomagnetic Index measures disruptions in the land magnetic field and is used to characterize the magnitude of geomagnetic storms, especially through the planetary index K or KP Index. The latter uses a series of magnetometers distributed in stations located in various parts of the planet. The indices above kp = 5 are associated with a specific degree in the geomagnetic storm scale Employed by the NOAA SWPC, being G1 (minor) the smallest category on the scale and G5 (extreme) the category that denotes the strongest storms, those of index Kp = 9. A G4 storm. The storm recorded on Sunday, with a Kp = 4 index led the center to alert a “severe” or G4 geomagnetic storm. In your noticethe SWPC pointed out that, in addition to intense northern lights and lower latitudes than usual, possible impacts on infrastructure and networks, including problems with satellites and loss of precision in the GPS. The Category events They usually imply possible problems with voltage control that can also cause “mitigable” problems in electrical networks. At space vehicles, the SWPC indicates that these storms are associated with possible monitoring problems that require future corrections. Finally, other possible impacts are on the spread of HF radio signals and low frequency radio navigation. An active solar cycle. The situation has stabilized With ups and downs And, although the last one average three -hour data from the KP index is 6, the SWPC has already reduced the intensity of the storm to G1, or minor storm. The last months have been revolts as far as spatial meteorology is concerned. In October 2024, A similar situation He brought spectacular dawn. According to estimates From the experts we are already after the peak of activity of solar cycle 25, but we have not yet moved away much so the solar activity remains intense. Perhaps this is not the last storm of these characteristics that we see in the coming months. In Xataka | We have detected the exact date on which the most brutal solar storm occurred in history.

Severe climate will cause rains with sudden floods in southern US

by

He southern United States It is under threat of severe climate For a storm system that is expected to move from southern California to Texas on Wednesday, causing rain and possible sudden floods. Santa Barbara County recorded the greatest amount of rain, with 2.23 inches, earlier this week, while Los Angeles recorded 1.62 inches and Santa Monica 1.38 inches. The west storm will reappear in the states of the southern plains late on Wednesday afternoon and during the night, with Possible severe climate in the center and north of Texas, including Dallas. In addition, this storm system will bring very strong rains and threat of sudden floods from Texas to western Kentucky, including Dallas, Texas; Little Rock, Arkansas; Memphis, Tennessee and Paducah, Kentucky. At the local level, some areas could see more than 4 inches of rain, which will cause sudden floods on Thursday, said ABC News. Winds and snow to the northern US Several fast -movement storm systems combined with the lake effect will bring strong winds and snow to parts of the great lakes and the northeast from today to Thursday. Early Tuesday, a snowstorm storm warning was issued for Syracuse, New York, where visibility was falling almost zero in some places. At least five states were this morning under snow and wind alerts from the west to the northeast. The most intense snowfall and the strongest winds will occur from northern Michigan to west of Pennsylvania and New York and northern New Englandwhere 30 cm of snow with wind bursts close to 96 km/h are predicted locally. In some of these most intense snow bands, bleaching conditions may occur. Further south and east, in the I-95 corridor, it is possible that they fall between 2.5 and 2.5 cm of snow from the Hudson Valley in New York to Connecticut and Massachusetts. Boston and Hartford could see snowfall.

Keep reading: Newsom signs order to speed up fire debris removal during the weekend There will be a drop in thermometers as humidity enters southern California from the north.which brings the possibility of light rains, with the threat of causing landslides in areas burned by the fires. NWS canceled previous weather alert due to fire risk and was replaced by a red flag warning for high winds. Humidity levels will remain very low, between 2 and 10%. Winds from the northeast are forecast to reach 20 to 30 miles per hour with gusts up to 50 miles per hour. More intense winds will be recorded in mountainous areas.
