The us state of florida is preparing for hurricane idalia, which is expected to make landfall later. the state governor has issued evacuation orders, amid warnings of isft high storm surges in some coastal areas. 0ur correspondentjohn sudworth has sent this report from the city of tampa. the unusually warm conditions in the gulf of mexico have fuelled the hurricane. though it s not the wind speeds that pose the greatest threat to life, but the storm surge, as large amounts of sea water are forced into florida s low lying coastal communities. with more than 20 counties under evacuation orders, for days, the authorities have been warning those residents unable to stay with friends or relatives to head for the emergency shelters. it s difficult for me to understand, because this is my first evacuation in my entire life and it s just difficult.
