Hazardous Weather Outlook National Weather Service Lake Charles LA 548 AM CDT Thu Apr 18 2019 LAZ027>033-041>045-052>055-073-074-TXZ180-201-215-216-259>262- 191100- Vernon-Rapides-Avoyelles-Beauregard-Allen-Evangeline-St. Landry- Calcasieu-Jefferson Davis-Acadia-Lafayette-Upper St. Martin- Vermilion-Iberia-St. Mary-Lower St. Martin-West Cameron- East Cameron-Tyler-Hardin-Jefferson-Orange-Northern Jasper- Northern Newton-Southern Jasper-Southern Newton- 548 AM CDT Thu Apr 18 2019 This Hazardous Weather Outlook is for portions of central Louisiana, south central Louisiana, southwest Louisiana, west central Louisiana, and southeast Texas. .DAY ONE...Today and Tonight An upper level storm system along with a surface cold front will clash with a moist and unstable air mass to produce showers and thunderstorms with the potential for severe weather as it crosses the area today. An Enhanced Risk (30 percent) that severe weather will occur within 25 miles of a point is outlined roughly east of a Leesville to Cameron line. The primary hazard with the severe storms will be damaging wind gusts, although there is a small chance (5 to 10 percent) for tornadoes and/or large hail. West of a Leesville to Cameron line to the Sabine River, a Slight Risk (15 percent) of severe weather is outlined, mainly from damaging winds and/or large hail. In addition, there is a Slight Risk (10-20 percent) of excessive rainfall leading to flooding east of a Leesville to Abbeville line, and a Marginal Risk (5-10 percent) of excessive rainfall leading to flooding across the remainder of southwest Louisiana and all of southeast Texas. This will be mainly from street flooding due to high rainfall rates falling in poor drainage areas. Also, high tides along the coast may back- up some drainage systems in lower Acadiana that run into the Gulf. Due to strong south winds ahead of the front, tides will run about 1 to 2 feet above predicted levels that may cause some water run up along the coast and minor coastal flooding for lower Acadiana and the lower Atchafalaya Basin. Also, a Wind Advisory is in effect for the late morning and afternoon hours for lower Acadiana as sustained winds in excess of 20 mph are expected. All the showers and storms are expected to move east of the Atchafalaya River by early evening. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Drier and cooler weather is expected for Friday before temperatures begin to moderate as we move through the weekend. Rain chances return to the region by the middle of next week as the next storm system approaches the area. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. GMZ430-432-435-450-452-455-470-472-475-191100- Sabine Lake-Calcasieu Lake-Vermilion Bay- Coastal waters from Cameron LA to High Island TX out 20 NM- Coastal waters from Intracoastal City to Cameron LA out 20 NM- Coastal waters from Lower Atchafalaya River to Intracoastal City LA out 20 NM- Waters from Cameron LA to High Island TX from 20 to 60 NM- Waters from Intracoastal City to Cameron LA from 20 to 60 NM- Waters from Lower Atchafalaya River to Intracoastal City LA from 20 to 60 NM- 548 AM CDT Thu Apr 18 2019 This Hazardous Weather Outlook is for portions of Gulf of Mexico. .DAY ONE...Today and Tonight A Gale Warning has been issued for the coastal waters east of Cameron for late this morning and early this afternoon as wind gusts exceeding 35 knots look possible. Otherwise small craft advisory conditions are expected on the coastal waters as low pressure deepens over the Plains States, tightening the pressure gradient over the northwest Gulf of Mexico. Widespread showers and scattered, sometimes strong thunderstorms will develop along and ahead of a passing cold front today. Behind the front, a strong offshore flow is forecast to develop...with gale force wind gusts again likely late tonight. .DAYS TWO THROUGH SEVEN...Friday through Wednesday Once winds diminish on Friday, no hazardous weather is expected through early next week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. 25
