Spurious echo is very light and of very little areal coverage, hence the minor flag. ************************************************************************************************ 26 Aug 99: Scattered convection present along weakening sea breeze at the start of the day quickly dissipates. Scattered, unorganized cells (mostly weak) develop over the Atlantic and move eastward into radar range by 10Z. Scattered activity continues offshore and is joined by cells over land, northwest of the radar, after 17Z. Cells greatly decrease in number after 21Z and only a few isolated cells persist through the end of the day.

Very quiet through most of midday as subsidence from nearby Hurrican Dennis suppresses activity. By 11Z, breakaway convective bands from Dennis begin to enter the 150 km range of the radar. Convection, mainly over the Atlantic, is locally heavy, but the more intense rainbands closer to Dennis' center due not eneter radar range until after 20Z. Heavy precipiation 100 km offshore continues through the end of the day.

Strong convection present within range until 14Z. After MCS has moved out of range, more cells begin firing and organizing themselves south of the radar. These cells eventually merge inot a strong line which meanders northward before moving out of range to the west, leaving a large stratiform region within range. Precipitation persists through the end of the day.
