Waves of #rain & #thunderstorms are expected to continue over portions of the #South this week, with forecasters warning of #FlashFlooding alongside other threats that accompany severe weather, especially across #Texas, #Louisiana & #Mississippi. In Texas, a search-&-rescue effort recovered the body of a 10-year-old girl who was swept away by floodwaters on Monday.

"Potentially catastrophic flooding could occur in the mid-South and Ohio Valley regions as multiple bouts of #ExtremeRainfall impact those regions into the weekend.
Rainfall totals could reach 10 inches or more in what some National Weather Service offices are calling a "particularly dangerous situation" that will produce life-threatening #FlashFlooding as well as major flooding that could approach record levels in some locations. "
"#ClimateChange is bringing heavier rainfall extremes and increased, inequitable flood risk to many parts of the U.S.
For every 1°F of warming, the air can hold 4% more moisture, increasing the chances of heavier downpours that contribute to #FlashFlooding hazards. "

Risk rises for #mudslides around #LACounty fire zones; prepare for worst-case scenario, officials warn
Alene Tchekmedyian, Rong-Gong Lin II, Melody Gutierrez, LA Times

"With more rain on the way, officials warned Sunday of an increasing risk of mudslides in #LosAngelesCounty's burn areas, with a 10% to 20% chance of significant #FlashFlooding and #DebrisFlows capable of damaging roads and homes in and around areas devastated by #wildfires.
"'This is the worst-case scenario to prepare for,' said Kristan Lund, a meteorologist with the National Weather Service in Oxnard.
"'We do have increasing concern for the #BurnScars,' Lund said. The charred footprint of the Eaton fire, which blackened more than 14,000 acres, is the most worrisome. 'These #FlashFloods and these debris flows could happen in and near or below these burn scars.'
"A #FloodWatch took effect at 10 a.m. Sunday and was set to continue through 4 p.m. Monday for the burned areas of the #EatonFire in the #Altadena and #Pasadena areas; the #PalisadesFire and #FranklinFires in the Pacific Palisades and Malibu areas; the Hughes fire around Lake Castaic; and the Bridge fire in the San Gabriel Mountains west and southwest of Wrightwood. The flood watch started six hours earlier than originally anticipated as rain began falling steadily around Los Angeles."

Ok folks, lots of #FlashFlooding around #MelbourneWeather areas.
Take it easy on the roads. Only travel if you really need to.

Our weekend storm system could give a winter wallop to areas north of us around the I-70 corridor. Some snow here, but also the potential for heavier rainfall with a marginal risk of #FlashFlooding possible.

#TropicalStormSara to unleash life-threatening #flooding in #CentralAmerica
Tropical Storm Sara will bring an extreme risk to lives and property in Central America where feet of rain may fall before tracking toward #Florida next week.
By Alex Sosnowski, AccuWeather senior meteorologist
Published Nov 14, 2024
"Rain may pour down for days on the northern parts of #Nicaragua and #Honduras before shifting to eastern parts of #Guatemala, #Belize and southeastern #Mexico this weekend.
"A general 8-12 inches (20-30 cm) will fall in this zone, but a large pocket of 12-18 inches (30-45 cm) of rain is forecast from northern Honduras and Nicaragua, with an AccuWeather Local StormMax™ of 50 inches (127 cm).
"'This amount of rain will trigger major #FlashFlooding and #mudslides with the potential for catastrophic loss of life and tremendous damage,' AccuWeather Chief Meteorologist Jonathan Porter warned.
"Some communities could be cut off for days due to washed-out roads and bridges or blocked by debris flows. Demands for rescue and recovery efforts, as well as food and medical supplies, will be great in the wake of the storm in the region.
"Because of Sara's proximity to the #Caribbean for several days, it will likely not unwind fully. As a result, winds, waves and #StormSurge will blast the coast of #Honduras, eastern #Guatemala, #Belize and Mexico's #Yucatan Peninsula. Sporadic #PowerOutages are likely due to #StrongWinds."

🚨 Weather heads up! An #AtmosphericRiver is set to bring heavy rain to the coast and mountain snow to the Pacific Northwest & Northern California this Wednesday. ⛰️ Meanwhile, thunderstorms and heavy rain could cause flash flooding in parts of the Lower Ohio, Tennessee & Mississippi Valleys. 🌧️ Stay safe & stay informed! #FlashFlooding #StormAlert #Weather
Current sitution in #NorthCarolina, as best I can piece together:
EasternNC: #tornadoes continue to be a threat.
CentralNC: sporadic tornadoes, but the worst mostly seems to have moved north
Western Piedmont/Foothills: major (and I mean potentially catastrophic) #flashflooding is coming your way, even after #Helene moves through and the sun is shining again.
WesternNC: seems like the rain has passed, but OMG the #flooding is the worst in history.
#WDEFWeather #News12Weather -- #FloodWatch extended to include all counties in the @WDEFNews12 viewing area except Grundy County #TNwx.
Heavy rain on top of already saturated ground will increase #flashflooding risk. #TurnAroundDontDrown
Tropical Depression 10E:
"Slow-moving Tropical Depression Ten-E will bring very #HeavyRainfall to coastal portions of southern and southwestern #Mexico through the upcoming week. This heavy rainfall will bring a risk of significant #FlashFlooding and mudslides to the Mexican States of #Chiapas and #Oaxaca, particularly in areas near the coast.
"The depression is forecast to become a tropical storm while moving near the coast of southern Mexico on Monday or Tuesday. A Tropical Storm Watch has been issued for a portion of the coastline, where tropical storm conditions could begin on Tuesday.
"The system could strengthen more than forecast if it remains over water. Interests along the coast of southern Mexico should monitor the latest forecast updates, as a Hurricane Watch could be required for a portion of the coastline later tonight or on Monday.
"Convection has gradually become better organized today (22 September) in association with an area of low pressure that the NHC has been monitoring off the coast of southern Mexico. A recent scatterometer pass shows the circulation is closed, with a well-defined center and peak winds of about 35 mph (30 knots) over the southern semicircle. Therefore, a new tropical depression has formed in the eastern Pacific basin.
"The depression is nearly stationary, but a slow northeastward drift is expected to begin later tonight. The track forecast is challenging, as there is a large spread in the guidance regarding the potential path of the system. Much of the track guidance shows the system moving generally east-northeastward as it becomes captured within the broader circulation of a developing Central American Gyre. However, a couple of global models (ECMWF and UKMET) instead show a northward drift over the next couple of days. The NHC track forecast favors the first scenario, and generally lies between the simple and corrected consensus aids. However, this track forecast is of low confidence given the large spread in the models, and adjustments will likely be required with future issuances.
"The moist, unstable environment and very warm waters should be conducive for some strengthening of the system during the next couple of days. The NHC intensity forecast lies between the IVCN and HCCA aids, but it should be noted that there are some models indicating the system could reach hurricane strength. While this is not explicitly forecast, it certainly cannot be ruled out given the environmental and oceanic conditions, and interests along the coast of southern Mexico should monitor the latest forecast updates. The peak intensity of the system will be highly dependent on how long the cyclone remains over water before reaching the coast, which is quite uncertain given the track challenges described above.
"Based on this forecast, the government of Mexico has issued a #TropicalStormWatch for the southern coast of Mexico from Punta Maldonado to Salina Cruz."
