•Hebert / Poteat
(H/P) Technique (..continued..)
•ST 1.5 (25-30 knots
max sustained winds)
–Low Level Circulation Center is displaced from poorly organized convection (not necessarily dense convection) by at least
0.5 degrees latitude (30 nm) but
no more than 2 degrees (120 nm)
–For Cold Lows, convection MAY NOT be connected to other systems and a small area (< 3 degrees latitude
or 180 nm) of deep layer convection exists near the center.
–If the system
meets the requirements of either of the above statements, then the intensity is ST 1.5
