Tropical disturbance threatens Gulf Coast as New Orleans could see 10 inches of rain
According to the National Weather Service, the broad area of low pressure is currently over the Florida Panhandle and slowly drifting westward, with coastal areas of Alabama, Mississippi and Louisiana in its projected path.
'This system is forecast to continue moving westward, and could emerge or redevelop over the far northeastern to north-central portion of the Gulf later today or tonight, reaching the coast of Louisiana by Thursday,' the weather service said in its latest forecast.
Multiple flood watches have already been issued along the Louisiana coast.
The current forecast from the NWS office in New Orleans calls for three to five inches of rain in coastal Louisiana south of Interstate 10 Wednesday through Saturday, with the potential for up to 10 inches in some areas.
"Ponding of water in low-lying and poor drainage areas is likely," the weather service said, with the potential for more significant flooding in low-lying areas "if the higher end rainfall totals are realized."
Localized pockets of heavy rain are also possible in north Florida and the Panhandle on Wednesday, the NWS office in Tallahassee said, as the system moves away.
According to the National Hurricane Center, there is a 40% chance that the system will become a tropical depression.
'Environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could still form over the next couple of days before the system moves fully inland by the end of the week,' the weather service said.
Further intensification is unlikely, but if it were to become a named storm, it would be Tropical Storm Dexter.
The 2025 Atlantic hurricane season, which began June 1 and runs through the end of November, has gotten off to a relatively slow start.
In May, forecasters at the National Oceanic and Atmospheric Administration predicted there would be 13 to 19 named storms, with six to 10 becoming hurricanes and three to five of those becoming major hurricanes (with winds of more than 110 mph).
So far, there have been three named storms: Tropical Storms Andrea, Barry and Chantal.

Periods of storms expected this weekend throughout the Pittsburgh area
It's going to be a hot and humid weekend with periods of storms expected to move through the Pittsburgh area. First Alert: None at the moment WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos Temperatures once again have struggled to drop below 70 degrees in Pittsburgh early Saturday morning as we are in the midst of an unseasonably warm and very humid air mass. Presently, we are at 18 days this year with a low temperature of 70 degrees or higher, and there is a good chance we could be in second place for the greatest number of 70-degree warm mornings on record at Pittsburgh International Airport by the middle of next week. Our large scale weather pattern this weekend will be comprised of continuous heat and humidity accompanied by periods of storms. A frontal boundary has stalled out across our area and will likely meander between the I-70 to I-80 corridors with strong and deep moisture convergence near the boundary. Several impulses aloft in the atmosphere will be moving atop this boundary bringing periods of storms as they pass through. The first of which will move across our area between sunrise and noon today. There will likely be a break in the thunderstorm activity by early to mid afternoon before the next disturbance moves in with increasing shower and storm chances this evening. Temperatures will rise from the lower reach the mid 80s for most by early afternoon. Storms may produce microbursts with wind gusts peaking around 40-60 mph and isolated instances of pea to dime sized hail. Heavy rai and flash flooding will also be a threat with isolated amounts of 2-3" in areas that see repeated storms, but a majority of folks will see around 0.5". Additional showers and storms are likely overnight as waves of energy pass through. The overall coverage will decrease some with areas mainly north and east of Pittsburgh being favored hotspots for storms. Temperatures will be very warm as well as lows struggle to drop below the low-mid 70s for most. Sunday morning will begin with mostly cloudy skies and a few isolated showers, but it is likely that storm chances will ramp up pretty early in the day—likely before noon as the ground temperature needed to initiate storms will only be in the upper 70s to low 80s. Storm coverage will start to decrease and shift south of Pittsburgh by early evening with clearing skies and areas of fog by Monday morning. Next week, a series of disturbances rotating around the heat dome parked to our southwest will move our way bringing isolated periodic storm chances. Timing is still fluid with this activity but keep an eye out Monday evening through Tuesday morning. A stronger cold front is expected to arrive around July 30-31 which will bring near to slightly below normal temperatures accompanied by drier air to our region.

Is autumn already coming? Risk of heavy rain until the beginning of the week
Meteorologists are talking about a "summer monsoon" - an area of high pressure over the Mediterranean and Scandinavia is causing sweltering heat, while a disturbance has settled directly over Germany, causing continuous torrential rain. What is particularly striking is that this type of disturbance hardly moves and remains almost stationary over certain regions. The focus of this weather situation will be over southern Germany over the next few days. The German Weather Service (DWD) is warning of heavy rainfall and severe thunderstorms, with up to 150 litres of rain per square metre possible in southern Germany by Tuesday. The thunderstorms at the weekend are mainly concentrated in the southern regions of Baden-Württemberg and Bavaria. At the beginning of the week, the rain front swings in over the Alps. South of a line from Saarland to Dresden, precipitation is to be expected again and again up to and including Tuesday - partly showery, in places with thunderstorms, hail and strong to stormy gusts. Between the Black Forest and the Bavarian Forest, especially south of the Danube, there is an increased risk of heavy rainfall. Localised flooding and high water may occur. North of a line from Saarland to Saxony, the weather will often be friendlier - with repeated clearings and longer sunny spells. However, occasional showers or isolated thunderstorms are possible. Only temporarily "midsummery" again For Wednesday, 30 July, there are signs of a brief calming of the weather overall: An extension of the Azores High will temporarily push the remaining disturbances eastwards. Large parts of Germany will see more sunshine and temperatures will climb back up to a summery 27 degrees in some places. However, this friendly spell of weather is likely to be short-lived. According to current model calculations, the area of high pressure will not be able to maintain itself in the long term. The overriding weather situation leaves room for new disruptive systems to settle over southern and south-eastern Germany in particular. Big differences within Europe An extreme heatwave over Sweden and Norway is slowly subsiding. In parts near the Arctic Circle, up to 13 consecutive days of heat were measured. However, the heat could return as early as next week. In Portugal, temperatures are currently normal for this time of year and the weather warnings are at "yellow" level. There was a massive heatwave there at the end of June, which apparently led to excess mortality, particularly among older people. Italy is currently enjoying moderate weather, with isolated showers and temperatures of around 25 degrees. In Spain, there are currently frequent showers in Catalonia and the Balearic Islands, but it is hot in the south of the country, with temperatures of 34-36 degrees Celsius. Temperatures in Spain are generally lower compared to other years.
