The building's maintenance crew quickly mobilized to address the situation. Once the rainfall intensity decreased, they began mopping up water and cleaning the damaged sections. Despite the challenging circumstances, the students relocated from the flooded areas to unaffected parts of the building, including the expanded women's section, where they continued their Torah study as the storm raged outside.
The National Weather Service issued a flash flood warning for Brooklyn and Manhattan shortly before 5:40 PM, which remained in effect until 7:45 PM, as intense rain moved through the city during rush hour. New York remained under a flood watch until 2:00 AM Friday morning, with forecasters warning that rainfall rates could reach approximately two inches per hour in certain areas.
While flooding at 770 during severe storms is not unprecedented, Thursday's incident was considerably less severe than previous events. This improvement is attributed to extensive drainage upgrades and repairs undertaken by the building's management to prevent water intrusion. In recent years, the historic structure has experienced various dramatic incidents, including a deliberate vehicle collision that caused substantial damage.
The timing of the flooding was particularly unfortunate, it occurred immediately after a thorough cleaning of the main study hall in preparation for the month of Tishrei, including work during the past week to clean and polish the floors.
