The effects of hurricanes Irma and Maria and a severe drought on the temperature, precipitation,and soil moisture (under canopy and in the open) were calculated at 22 sites from 0–1045m in northeastern Puerto Rico from 2001–2021, against the background short-term trend. Medianand minimum air temperatures increased uniformly across the elevational gradient, 1.6 times as fastin the air under the canopy (+0.08 °C/yr) and 2.2 times as fast in the soil under the canopy (+0.11°C/yr) as for air temperature in the open. There were no substantial moisture trends (average decrease
