Summary Although Tropical Storm Beryl brought heavy rains to NE Florida and SE Georgia, very little fell in the ACF River Basin so drought continues throughout most of the basin, with significant areas classified as extreme or exceptional Streamflows in the upper basin are in the range of 10 to 24% of historical observations, whereas streamflow levels in the lower basin are below any previous observations Groundwater in Miller County, GA remains in the range of the lowest 10% of historic observations Salinity levels in Apalachicola Bay are near 15 ppt at East Bay Bottom, 25 ppt at Cat Point, and 30 ppt at Dry Bar
Summary The 5-day outlook for rainfall is fair, with about 2 inches in the southern part of the basin but less than 1 inch in the northern part of the basin. Current ENSO conditions are neutral, but their remains about a 50% chance that El Niño will develop in the fall Both Colorado State U and NOAA forecast similar numbers of tropical storms and hurricanes for this summer, but the forecast does not predict where or whether these storms will make landfall The streamflow forecast for the next 1 and 3 months continues to show a high probability that streamflows will remain below normal
