forecast decreasing wind shear initially additionally hurricane roughly week earlier contributed decrease strength storm weakened reconnaissance aircraft observations august concluded structure improved compared previous day early august weakened extent minimal hurricane maximum winds mph time august national_hurricane_center noted soon leave track left likely lead intensification possibility strengthening increased predictions showed gradual intensification early august increase sustained winds decrease barometric pressure miles wide eye observed reconnaissance aircraft
