                              Heavy rainfall between 7 to 10 inches 
                              occurred in St. Mary's Charles, and 
                              Calvert countles. The heaviest rain 
                              totals of near 10 inches were reported 
                              in southeast St. Mary's County. The 
                              heavy rains contributed to the extensive 
                              downed trees and powerlines across Lower 
                              Southern Maryland

                              near 10 inches were reported in southeast 
                              St. Mary's County. The heavy rains 
                              contributed in the extensive downed 
                              trees and powerlines across Lower 
                              Southern Maryland.

                              The remnants of Tropical Storm Ernesto 
                              did not affect Charles County quite as 
                              severely as neighboring Calvert and St. 
                              Mary's Counties. However, gusty winds up 
                              to 50 mph still caused a few downed 
                              trees and powerlines, and isolated 
                              power outages. The reason for the 
                              downed trees  was due to a combination 
                              of heavy rainfall, which acts to weaken 
                              the roots of the trees, combined with 
                              the strong winds up to 45 mph. 32 
                              houses received damages from falling 
                              trees. In Anne Arundel County, a few 
                              trees were downed due to strong winds 
                              gusting as high as 45  mph. 
 
  MDZ017>018                  St. Mary's--Calvert 
                              01         1100EST 
                                         2100EST 
 
                              Catastrophic damages were sustained in 
                              extreme Lower Southern Maryland from the 
                              remnants of Tropical Storm Ernesto. Most 
                              of the damages were caused by the high 
                              winds, although damages were also 
                              sustained due to extensive storm surge 
                              flooding of coastal areas. 
 
                              High winds persisted for much of the 
                              day and evening in Lower Southern 
                              Maryland due to the remnants of Tropical 
                              Storm Ernesto moving as through the Mid 
                              Atlantic. Wind gusts as high 60 mph were 
                              reported in St. Mary's County. Wind 
                              gusts as high as 70 mph were reported 
                              from the public, however these winds 
                              were not able to be substantiated. These 
                              winds, coupled with heavy rains, caused 
                              extensive tree and powerline damage 
                              around the county. The most extensive 
                              damages occurred along Murray Road in 
                              the town of Ridge. The damages to trees 
                              and powerlines were explained by local 
                              residents as more extensive than during 
                              Hurricane Isabel in 2003. St. Mary's 
                              County Government reported total cost 
                              of direct weather related damages, 
                              including the added cost of manpower to 
                              respond to damages and debris removal, 
                              at $4.4 million. The damage cost 
                              reported in Storm Data is estimated at 
                              $3.30 million for St. Mary's County for 
                              damages to private and public property 
                              and restoring power systems. The Storm 
                              Data estimate does not include the 
                              costs of manpower and debris removal. 
 
                              High winds also occurred in Calvert 
                              with downed trees, powerlines, and 
                              subsequent power outages. The most 
                              extensive damages in Calvert County 
                              occurred close to the Chesapeake Bay, 
                              in the communities of Cove Point and 
                              Solomons Island.

                              Heavy rainfall between 7 to 10 inches 
                              occurred in St. Mary's, Charles, and 
                              Calvert counties. The heaviest rain 
                              totals of near 10 inches were reported 
                              in southeast St. Mary's County. The 
                              heavy rains contributed to the extensive 
                              downed trees and powerlines across 
                              Lower Southern Maryland.

                              MLLW late Friday. Moderate coastal 
                              flooding occurred due to the storm surge 
                              from the remnants of Tropical Storm 
                              Ernesto. In Charles County, mandatory 
                              evacuations were ordered due to the 
                              flooding, with many roads flooded. Piers 
                              and bulkheads were also damaged along 
                              the western shore of the Chesapeake. 
                              Tide crest was 4.45 MLLW in the upper 
                              Tidal Patuxent River late Friday.

                              The National Weather Service conducted 
                              a storm survey in Severna Park and 
                              Pasadena Maryland, rating the tornado 
                              an F1 on the Fujita scale of tornado 
                              intensity. It was determined that a the 
                              tornado touched down intraveled two 
                              miles the area of Severna Park about 
                              6:34 pm, and before lifting in Pasadena 
                              around 6:44 pm. At its maximum the storm 
                              was 250 yards wide with winds of 90 mph. 
                              34 homes were severely damage by falling 
                              trees with 13 of those homes rendered 
                              uninhabitable. Initial minor damage was 
                              located near the intersection of Ritchie 
                              Highway and McKinsey Avenue. A hardware 
                              store had its sign blown down and a 
                              small tree was downed near the Severna 
                              Park Marketplace Shopping Center. A 
                              few trees were also downed  immediately 
                              behind the shopping center along Leelynn 
                              Road. The tornado gathered strength as 
                              it progressed through West Ridge and 
                              towards Cattail Creek off of the Magothy 
                              large hardwood trees of one to two feet 
                              in diameter were uprooted, and several 
                              others were snapped off along Whittier 
                              Parkway. Two of the large trees had 
                              fallen through houses. These trees, as 
                              most of the trees were in the survey, 
                              were blown down nearly perpendicular to 
                              the path of the tornado (knocked down 
                              towards the west). The tornado then 
                              reached its most intense and widest 
                              extent as it passed through the 
                              community of Lower Magothy Beach. Many 
                              of these trees knocked down in this 
                              area were large two foot diameter 
                              hardwood trees that were 60 to 80 feet 
                              tall. Leaf spatter was noted on the 
                              sides of homes and vehicles. Slight 
                              siding damage was noted on one home. 
                              Many wires and telephone poles were 
                              knocked down in this area. The width of 
                              the tornado at this point was 250 yards. 
                              Damage became much more limited as the 
                              tornado continued north across Norwich 
                              Road and Inverness Road in Riverdale. 
                              By the time the storm crossed the
