We're up to twelve days in a row of rainfall around the region and there's more on the way, with help from a player in the Gulf of Mexico. A "blob" of disorganized storms, or "tropical entity" as we've been calling it, could actually become a true Tropical Depression today -- experts at NOAA's National Hurricane Center now give it a 50% chance -- before crashing the West Gulf coast tomorrow. No matter what call it, heavy rain looks to be the outcome. The forecast calls for potential 1" to 2" totals around Austin and maybe some heavier 2" to 3" totals in the San Antonio area, with heavier accumulations possibly creating flash floods further south and west of the Alamo City. In the above video, Chief Meteorologist Burton Fitzsimmons shows us the latest satellite and radar imagery, and gives us an update on where computer models suggest it'll all go. As the forecast could change quite a bit during the next 24 hours, be sure to watch 'Weather on the 1s' on TV or via the live stream for the very latest.<doc-sep>Texas Gov. Greg Abbott issued a disaster declaration Friday in advance of an approaching weather disturbance in the Gulf of Mexico that is expected to bring severe weather to the coast and South Central Texas. "The tropical disturbance impacting the Texas coast poses a threat of imminent disaster, including severe flooding, property damage and potential loss of life," Abbott said. "While we stand ready to deploy state resources to assist local officials in their response efforts, it is critical that all Texans in the storm's path are prepared to ensure their own safety."<doc-sep>Though the chances of a tropical cyclone developing this weekend in the Gulf of Mexico have decreased to 50 percent, the rain expected from the weather system could still break records in San Antonio. The Alamo City is roughly four inches away from breaking the September rainfall record set in 1946, when 15.78 inches of rain were recorded at the airport. A flash flood watch will take effect at 7 a.m. Friday and is slated to last through 7 p.m. Saturday for portions of South Central Texas, including San Antonio. RELATED: Fleeing Florence, some Carolinians are landing in S.A. "It won't take much (to break the record)," said Paul Yura, National Weather Service meteorologist. Forecasters are expecting 2-4 inches of rain, with isolated pockets receiving up to 8 inches. Most of the rain is expected to fall in San Antonio's metropolitan area, the western Hill Country and the Coastal Plains. Local authorities are urging residents to be careful because the constant rain this month saturated the soil in the region, meaning that even a small amount of rain can lead to flash flooding. A flood watch has been issued in San Marcos, effective on Friday and Saturday, in anticipation of the rain. Texas Department of Transportation dispatched several vehicles from Austin on Thursday to the San Antonio area.

The crews will be prepared to dispatch anywhere they are needed, including Corpus Christi and the Rio Grande Valley, where the storm is expected to make landfall. The equipment on-hand includes dump trucks, Bobcat tractors, excavators, and street sweepers. Yura said there is a silver lining after this weekend's storms — drier weather and clearer skies next week.<doc-sep>
National Weather Service meteorologists said Monday that there's a 50 percent chance a system they are monitoring in the Gulf of Mexico may develop into something more serious. Meteorologist Melissa Huffman said because it's early on in the system's development, forecast models are split on the chances of a tropical cyclone's development. "If it does develop, there could be impacts on the Texas coast," Huffman said. RELATED: NWS extends flash flood watch for Bexar County, as soaked soil increases flooding chances Texas Gov. Greg Abbott announced he is taking precautions in light of the news, increasing the Texas State Operations Center readiness level to Level III. The change allows requests for emergency aid and increases coordination activities. "We are closely monitoring a tropical system expected to approach the Gulf of Mexico and potentially impact the Texas coast in the coming days," Abbott said in a statement. "In light of recent heavy rainfall across the state, we are on high-alert as any additional rain could quickly create dangerous flash flooding conditions. I urge all Texans to take precautions and review their emergency plans now to prepare for any potential impact to their community." Even if a storm doesn't develop, Huffman said, the region would still be looking at a chances of heavy rain as the moisture from that system makes landfall, which won't happen until at least the weekend, the forecast showed. Regardless, Texans should keep a close eye on any storms developing in the gulf during hurricane season. "We want to make sure people are thinking about potential issues that come up here closer to home," Huffman said. San Antonio saw steady rainfall last weekend, and more rain is expected throughout the week.
