Mexico: Adverse weather conditions forecast across southern and southeastern regions through at least June 23
Severe weather forecast across parts of southern and southeastern Mexico through June 23. Possible flooding and associated disruptions.
Event
Severe weather is forecast across parts of southern and southeastern Mexico through at least June 23. Successive tropical waves will interact with low-pressure channels to bring heavy rainfall and possible thunderstorms across the region over the coming days. Strong winds, lightning, and hail may accompany storms. Rainfall totals of 7.5-15 cm (3-6 inches) are forecast in parts of Chiapas State June 20-23 and Quintana Roo June 22. Totals of 5-7.5 cm (2-3 inches) are expected in parts of Oaxaca June 20-22, Tabasco and Veracruz June 22, and Campeche and Quintana Roo June 23. Totals of 2.5-5 cm (1-2 inches) are expected across other parts of the affected area June 20-23. The heavy downpours could trigger flooding in low-lying areas and landslides on unstable slopes.
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rainfall has saturated the soil.
The severe weather will likely contribute to transport disruptions throughout affected regions. Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Severe weather will also likely trigger flight delays and cancellations at airports across the affected region. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas with heavy rainfall and potential track inundation.
Advice
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Confirm flights.
During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating; drink bottled or boiled water. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in the case of prolonged electricity outages.
