I turn the corner onto the Thames Path and the sky opens out ahead of me, blue with white clouds scatted across it. The tide is at its lowest point and the river seems calm. This stretch of the river is ripe with new development in every direction and NOAA's signal weaves in and out of the towers as I listen. The pass rises to my north at Bow Creek, moving west across the sky, setting behind the new residential development under construction at Canary Wharf. The towers obscure the signal for the final minutes of the pass, so as I turn back towards the skyline all I hear is static, fading in and out of the tide as it crashes against the stone wall of the embankment.
