Iran, Iraq, Kuwait: Adverse weather forecast across the region through at least May 3

Severe weather is forecast across much of Iran, Iraq, and Kuwait through at least May 3. Heavy rainfall and thunderstorms are expected across parts of the region over the coming days. Storms may be accompanied by strong wind gusts, lightning, and possible hail. Heavy downpours may trigger flooding in low-lying areas and landslides on unstable slopes. Strong winds may cause property damage and power outages.

Iranian meteorological authorities have forecast scattered showers in northern and western regions April 29 before a weather system moves into western regions April 30 and spreads across central and southern regions through May 3, bringing at times heavy rainfall and thunderstorms to the affected areas. Strong winds may cause dust storms in eastern regions and rough seas in coastal areas over the coming days.

The Iraqi Meteorological and Seismology Organization has forecast light showers and storms across much of the country April 29. Moderate-to-heavy rain and thunderstorms are expected across parts of the country April 30-May 3. The heaviest rainfall is likely in eastern areas, where flash flooding is possible. Strong winds may cause dust storms in central and southern parts of the country and a drop in temperatures is expected across much of the country,

The Kuwait Meteorological Department has issued a weather watch (the lowest level on a two-tier scale) for fresh winds and thunder rain April 29. Winds gusting over 60 kph (37 mph) are possible and lead to reduced visibility due to dust storms. Scattered rainfall, isolated thunderstorms, and rough seas are also expected, There is a further chance of rainfall, thunderstorms, and dust storms over Kuwait April 30-May 1 before rainfall starts to decrease from May 2.

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 or a lack of stormwater drainage systems. Sites 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 the soil has become saturated by heavy rainfall.

Authorities may issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant winds, flooding, and/or landslides impact utility networks.

Due to the arid nature of the region and poor stormwater management in some urban areas, even minor rainfall accumulations could quickly result in episodes of flash flooding. Flooding is possible in streams and wadis (dry riverbeds). Significant rainfall may be preceded by moderate winds and dust storms, though some areas - particularly desert areas - may experience high levels of dust without rain.

The severe weather could contribute to transport disruptions throughout the affected area. Floodwaters and debris flows could render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Traffic and commercial trucking delays might occur along regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Strong winds may also pose a hazard to high-profile vehicles.

Hazardous weather conditions may cause flight delays and cancellations at airports in the region. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas that see heavy rainfall and potential track inundation.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
