On annonce 37 degrés celsius a moosonee et le record précédent est de 35.6 degré celsius(j'ai pris cet info sur le site de MM)pour un 11 juillet il sera sans doute battué...mais ma question est quel est le record absolu pour cette région?

Dennis va probablament tres tres bientot passer la catégorie 5 ...car l'ouragan génère des vents de 150mph...pour qu'un ouragan soit de catégorie 5, les vents doivent être de plus de 156 mph...et depuis 8 heures ce matin Dennis a augmenter de 15-20mph la vitesse de ses vents soutenus...c'est fou Voici la discussion de AW a 11 ce matin DENNIS REMAINS A DANGEROUS CATEGORY 4 HURRICANE WITH SUSTAINED WINDS OF 150 MPH As of 11:00 a.m. EDT, Hurricane Dennis was centered at 21.4 north, 79.9 west, or about 250 miles south-southeast of Key West, Fla., Maximum sustained winds are 150 mph, with higher gusts. The threshold for a category 5 Hurricane is 156 mph. The estimated central pressure is 938 mb (27.70 inches). Dennis is moving toward the northwest at 15 mph. The aircraft reports, and the satellite shots do seem to indicate more of a west to northwest movement; perhaps this is wobbling effects of the storm. A HURRICANE WARNING IS IN EFFECT FOR CUBA FOR THE PROVINCES OF LA HABANA...CIUDAD DE LA HABANA...MATANZAS... VILLA CLARA... CIENFUEGOS...SANCTI SPIRITUS...CIEGO DE AVILA...CAMAGUEY...LAS TUNAS...GRANMA...SANTIAGO DE CUBA...HOLGUIN AND GUANTANAMO. A HURRICANE WATCH REMAINS IN EFFECT FOR THE ISLE OF YOUTH AND THE PROVINCE OF PINAR DEL RIO. A HURRICANE WARNING IS IN EFFECT FOR THE LOWER FLORIDA KEYS FROM THE SEVEN MILE BRIDGE WESTWARD TO THE DRY TORTUGAS. A TROPICAL STORM WARNING AND A HURRICANE WATCH IS IN EFFECT FOR THE REMAINDER OF THE FLORIDA KEYS...EAST OF THE SEVEN MILE BRIDGE TO OCEAN REEF AND FLORIDA BAY. TROPICAL STORM WARNING FOR CAYMAN BRAC AND LITTLE CAYMAN ISLANDS. ALL WARNINGS HAVE BEEN DISCONTINUED FOR GRAND CAYMAN ISLAND. A TROPICAL STORM WARNING IS IN EFFECT ALONG THE FLORIDA WEST COAST SOUTH OF BONITA BEACH...AND ALONG THE FLORIDA EAST COAST SOUTH OF GOLDEN BEACH. A TROPICAL STORM WATCH IS IN EFFECT ALONG THE FLORIDA WEST COAST NORTH OF BONITA BEACH TO LONGBOAT KEY. Hurricane conditions, including life-threatening storm surge and flash flooding is occurring over central and eastern Cuba; these conditions will shift into western Cuba later today. We expect Dennis to track over the central and western part of Cuba late today, and end up in the southeastern Gulf of Mexico late tonight. All U.S. interests, from the Florida Keys and the Florida west coast, all the way to the Louisiana coast, should closely monitor the progress of this powerful hurricane. As of now, we believe Dennis will head for the central Gulf coast. Current thinking, as far as landfall, is between the mouth of the Mississippi River and Pensacola, Fla. There continues to be different ideas on the exact track. The interaction with the higher terrain of Cuba could alter the hurricane's structure and cause it to react differently to the steering currents. The upper-level high pressure ridge has weakened over Florida and the eastern Gulf while a strong upper-level disturbance is now diving into eastern Texas. This will help to maintain a weakness in the upper-level wind flow over the central Gulf and Dennis will turn northward ahead of this weakness. If the Atlantic high pressure ridge fails to build farther west Dennis could track close to the west coast of Florida. If the upper-level high pressure ridge builds stronger to the west, then Dennis will be diverted more toward Louisiana. As far as intensity changes, Dennis is a Category 4 and should lose at least some strength over Cuba today and tonight. Once the storm moves back over the southeast Gulf it should regain some strength. It has been pointed out by various sources that the depth of very warm water is less over the eastern Gulf of Mexico and this might prevent Dennis from strengthening. However, this is all speculation. As far as effects from Dennis, Cuba will be hit hard through today with torrential, life threatening flooding rainfall. The hurricane's growing circulation size will start to affect South Florida during the day today with increasing breezes and gusty showers. The rain and the wind will increase across the Keys, then into South Florida Friday night. Then, wind swept rain will spread northward over much of the peninsula of Florida during Saturday. Dennis's tropical-storm-force winds extend out to about 140 miles. So, our current projection would put tropical-storm-force winds along the west coast of Florida along with a storm surge of around 3 feet. Rainfall could be heavy enough over Florida to bring 3-5 inches to some places and that could lead to flooding. Tropical Rainstorm Cindy is moving northeastward out of the Chesapeake Bay area. Heavy, flooding rainfall is the main problem with what is left of Cindy; to the right of the track, there can be a few strong to severe thunderstorms. We expect Tropical Rainstorm Cindy will track up into New Jersey this afternoon. Tropical waves to note, even though Dennis is the main show right now: A tropical wave along 41 west, moving west; a tropical wave along 60 west south of 20 north, moving west.

Discussion de AW...Vent soutenu de 130mph a 8heures p-m!!!...D'apres moi ca va se rendre a la catégorie 4 avant datteindre cuba DENNIS IS NOW A DANGEROUS CATEGORY 3 HURRICANE WITH SUSTAINED WINDS OF 130 MPH AND IS HEADING FOR CUBA As of 8:00 PM EDT, Hurricane Dennis was centered at 19.4 north, 77.1 west, or about 135 southwest of Guantanamo, Cuba. Maximum sustained winds have increased to 130 mph, with higher gusts. The estimated central pressure is 951 mb (28.08 inches). This makes Dennis a strong Category 3 hurricane. If Dennis increases any more it will become a category 4 hurricane. Dennis is moving toward the northwest at 15 mph. Dennis should remain on this course over the next 24-48 hours. A HURRICANE WARNING IS ISSUED FOR THE LOWER FLORIDA KEYS FROM THE SEVEN MILE BRIDGE WESTWARD TO THE DRY TORTUGAS...AND A TROPICAL STORM WARNING IS ISSUED FOR THE REMAINDER OF THE FLORIDA KEYS...EAST OF THE SEVEN MILE BRIDGE TO OCEAN REEF AND FLORIDA BAY. A HURRICANE WATCH REMAINS IN EFFECT FOR THE FLORIDA KEYS EAST OF THE SEVEN MILE BRIDGE TO OCEAN REEF AND FLORIDA BAY. A HURRICANE WARNING IS IN EFFECT FOR THE PROVINCES OF MATANZAS... VILLA CLARA... CIENFUEGOS...SANCTI SPIRITUS...CIEGO DE AVILA... CAMAGUEY...LAS TUNAS...GRANMA...SANTIAGO DE CUBA...AND GUANTANAMO. A HURRICANE WATCH IS IN EFFECT FOR THE REMAINING PROVINCES OF CUBA INCLUDING THE ISLE OF YOUTH...PINAR DEL RIO...LA HABANA... CIUDAD DE LA HABANA...AND HOLGUIN. Very stormy conditions, including life-threatening flash flooding is imminent for most of central and eastern Cuba. We expect Dennis to track over the central and western part of Cuba Friday afternoon and early Friday night, and end up in the southeastern Gulf of Mexico, later Friday night. All U.S. interests, from the Florida Keys and the Florida west coast, all the way to the Louisiana coast, should closely monitor the progress of this strengthening hurricane. As of now, we believe Dennis will head for the central or eastern Gulf coast. Current thinking is over the western Florida panhandle. However, there continues to be different ideas on the exact track. The interaction with the higher terrain of Cuba could alter the hurricane's structure and cause to to react differently to the steering currents. The upper level high pressure ridge has weakened over Florida and the eastern Gulf while a strong upper level disturbance is now diving into eastern Texas. This will help to maintain a weakness in the upper level wind flow over the central Gulf and Dennis will turn northward ahead of this weakness. If the Atlantic high pressure ridge fails to build further west Dennis could track close to the west coast of Florida. If the upper level high pressure ridge builds stronger to the west the Dennis will be diverted more toward eastern Louisiana. On a historical note, this is the earliest in the Atlantic hurricane season that the "D" named storm has been reached. In no other season, back through the time in which records have been kept, have there been four named storms by this early date. Tropical rainstorm Cindy is located about 80 miles northeast of Asheville North Carolina and is moving northeast at about 20 mph. Heavy, flooding rainfall is the main problem with what is left of Cindy; to the right of the track, there can be a few strong to severe thunderstorms. We think Tropical Rainstorm Cindy will track up through the western Carolinas early tonight, and into Virginia by Friday morning. Tropical waves to note: a wave, or actually a 1014 mb low is centered near 11 north, 20 west; strong thunderstorms are nearby. This is a very large, impressive-looking system in the eastern Atlantic similar to what Dennis looked like about 10 days ago. A tropical wave is along 38 west, south of 20 north, moving west; no strong thunderstorms are associated with this system. A tropical wave is along 54 west, south of 16 north, moving west.

Et voila, comme prévue, l'ouragan Dennis a atteint la catégorie 3 depuis 5heures cette apres-midi avant d'atteindre cuba...Elle y fonce maintenant avec des vents destructeurs de plus de 110 mph...Elle perdra un peu de force en survolant Cuba mais la reprendra aussitot rendue dans le golf du Mexique...Elle pourrait atteindre la catégorie 4 avant d'atteindre les cotes américaines mais c loin detre sur...En attendant jespere que les gens de Cuba sont bien a l'abri car ca va brasser!!!

En passant, un autre systeme a surveiller...il se détache présentement de la cote Africaine...Si ce systeme survis aux eaux un peu plus fraiches de cette région de l'atlantique, il pourrait peut-etre devenir Emily...

J'ai regarder l'image visible de louragan...il commence vrmt a etre bien oraganisé...on peut meme voir loeil sur l'image visible...la jamaique et lest de cuba vont vraiment y gouter ...Je crois meme qu'avec les eaux chaudes du golf du Mexique et l'absence de d'autres bons systemts pres de Dennis, cette ouragan pourrait se retrouver de force 4 selon moi

Selon le graphique tendance 14 jours de MM, il y aurait effectivement une canicule a partir du 11...le 13 serait la journée la plus chaude et le tout se finirait le 14...

Le tonerre de tout a l'heure est maintenant accompagner de flash mais je ne saurais dire si il tombe des éclairs pres de chez moi car des arbres entoures ma maison

Méchante cellule a la frontiere, elle se dirige est nord est...tres prometteur pour l'estrie et c'est cette cellulle qui donne du tonerre dans mon secteur, mais le gros se passe au sud...bonne fin d'apres-midi en vue et le début de soirée également!

J'habite a granby, c pas si loin de st-hyacinthe ou il y a veille, et depuis quelques minutes le tonerre gronde et il pleut...On verra bien

Voici les prévisions de Accuweather pour ma région(granby) cette apres-midi...tres prometteur!!! Tuesday Variable clouds, a few strong thunderstorms High Temperature: 28° C RealFeel®: 31° C Winds: W at 9 kph Wind Gusts: 20 kph Maximum UV: Moderate (4) Thunderstorm Probability: 100% Amount of Precipitation: 1.65 cm Amount of Rain: 1.65 cm Amount of Snow: 0 cm Hours of Precipitation: 4 hrs Hours of Rain: 4 hrs

Selon la carte foudre, la cellule orageuse dont tu parles ne donnent plus aucune éclair depuis qu'elle a passé Montréal...je n'ai pas vérifié par contre si elle donnait encore des averses...

Géniale les photos en particuler celle de lentonnoir!
